40 = 2^3 * 5
1400 = 2^3 * 5^2 * 7
LCM(2^3 * 5, 5^2 * 7) = 1400
so x = 175
1400 = 2^3 * 5^2 * 7
LCM(2^3 * 5, 5^2 * 7) = 1400
so x = 175

First 1400=2^3*5^2*7
40=2^3*5
Then we take non common one and common with the biggest power
x=2^3*5^2*7 can be one answer but the question says an odd number the other possible outcome would be x=5^2*7=175,this is because 2^3 had chance to be in x and also not to be in x.

1400=2^3×5^2×7
40=2^3×5
LCM(40,1400)=2^3×5^2×7
X=5^3×7(25×7)=175
X IS 175
40=2^3×5
LCM(40,1400)=2^3×5^2×7
X=5^3×7(25×7)=175
X IS 175
