Question

Question1: find the least perfect squared number that is divisible by 12, 16,20 and 24

Answer 1

12 = 4*3
16 = 4*4
20 = 4*5
24 = 4*6 = 4*2*3

perfect squares come in pairs of equal factors

so we need 4*4*25*9 = 3600

Answer 2

Question1: find the least perfect squared number that is divisible by 12, 16,20 and 24.




Plz change the method of this question this method
I cannot Understand the first solving method of this question

Answer 3

Can you please change the method of this question.

Answer 4

12=4*3
16=4*2*2
20=4*5
24=4*3*2

Highest common factor =4*2*3=24

Least perfect square number =24*5*2 =24^2*5^2*2^2
=376*25*4 =376*100
Answer is =37600

Answer 5

12 = 4*3
16 = 4*4
20 = 4*5
24 = 4*6 = 4*2*3

perfect squares come in pairs of equal factors

so we need 4*4*25*9 = 3600
is the right method and 3600 is the right answer.but it is little bit tricky.
NOTE:perfect squares come in pairs of equal factors
we have four (4) so there are two (4)in the last step.
we have two (3) so there are only one(3)in the last step.
we already have 5 so we need an extra 5 to make perfect square.
12=4*3
16=4*2*2
20=4*5
24=4*3*2

Highest common factor =4*2*3=24

Least perfect square number =24*5*2 =24^2*5^2*2^2
=376*25*4 =376*100
Answer is =37600
This answer is totally wrong

Answer 6

3600

Answer 7

my answer is 1440

Answer 8

1440 is not perfect square
