Find the value of an odd natural number x if LCM(x, 40)=1400
Steve
x must divide 1400, which is 2*7*2*5*2*5

Can you make a guess now?

40=2*2*2*5 1400=2*2*2*5*5*7 X= 5*5*7
ABAYNESH BIZU
40=2*2*2*5 1400=2*2*2*5*5*7 X= 2*2*2*5*5*7 IS THIS CORRECT

The LCM of x and 40 is 1400
x is odd. tale the prime factorization.
1400 = 7 × 2 × 2 × 2 × 5 × 5
40 = 5 × 2 × 2 × 2
The common factors of both 1400 and 40 are: 5 × 2 × 2 × 2
= 40, which means the
GCD is 40
if GCD is 40 then other number is 1400
as if smallest number divides greater number then smaller number is GCD and greater number is LCM.
However, this is impossible since 1400 is even. Therefore,
1400/40 = 35
if other number is 35,
then LCM of 40 and 35 is 280
1400/280 = 5
so other number is 35 × 5 = 175
175 = 5 × 5 × 7
40 = 5 × 8
LCM = 5 × 5 × 7 × 8 = 1400
so x = 175
value
175

No answer, am confused ????sorry

Simply x=175

Some times we can get LCM of two numbers by the products of the numbers
That means
40*a=1400
a=1400/40
Therefore,a=35

the LCM of 40&1400=280 but 1400/280=5,then x=35*5=175

(X.40)=1400 1.by prime factorization 40=(2)(2)(2)(5) 1400=(2)(2)(2)(5)(5)(7) =(5)(7)=35 =(5)(5)(7)=175 so X=35

To Find The Value Of 'X' First LCM (X,40)=1400 Then LCM 1/40 (X,40)= 1/40(1400) X=35 Then LCM (35,40) 35=35,70,105,140,175,210,245,280 40=40,80,120,160,200,240,280 The LCM(35,40)=280 Then The LCM Of (X,40) Divided By LCM Of (35,40) &Multiply By '35' Is Equals To The Value Of 'X' Then 1400/280=5 & 5*35=175 then the value of 'x' is equals to 175 x=175

x=2n+1,40=2^3*5,then( 2n+1)*40=1400,n =17,so, x=35 again GCF(35,40)=5 ,so the odd natural number is y =35*5=175

the tow Number Lcm are

If Lcm (x,40)=1400

# Lcm Valu divided by given Valu we get soln

# find Lcm of Soln Valu And Give valu we getLcm

# Lcm valu divided by we get valu We get valu

# finally get soln multiplied by get valu

Let,x=the set of odd number so lcm(x,40)=1400 ,x=2n+1so we replace x by 2n+1 and we get (2n+1)*40/40=1400/40 then 2n+1=35 then minus from both side 1 and we divide both side by two we get 35 the gcf of 35 and 40 =5 we multiple the result 35*5=175

The answer is not 35.

The answer is simple:
First, let's divide 1400 by 40
We get 35, then insert it in x i.e. (35, 40)
Find the LCM of (35, 40) which is 280
Divide 1400 to 280 the result will be 5
Then, multiply 5 & 35, the answer will be 175

the prime factorization of 40=2*2*2*5 and the prime factorization of 1400=2*2*2*5*5*7 then the LCM of both is the highest factorization of x and 40 then the remain factorization is the factorization of x=5*5*7=175

Find an odd natural number x such that LCM (x,40) = 1400

solution
1st, We multiply x*40= 1400
x= 1400/40
x= 35
2nd find the LCM 40&35
LCM 40&35 is 280
280 is other LCM 35&40
3rd we divide 1400 by 280, then we have gate 5
1400/260=5
4rd we multiply value of x and value of 1400/280
so, 35*5 = 175
finally an odd natural number is 175

Ashlee worked 1,944 hours last year. She earned $14 for each hour she worked.
She wants to use her earnings to buy a new vehicle.

40=2*2*2*5 1400=2*2*2*5*5*7 X= 5*5*7 THIS CAN'T BE ANSWER!
Because, what if 2*2*2 or 2*2 or 2 present in x? this is my opinion.

LCM(X,40)=1400.
from the given LCM we have X×40=1400
=>X=35
& when I substitute for X in GCF.
GCF(35,40)=5
SO, X×40=1400×5
WE get the value of =>X=175
.•.X=175
