Lets's calculate LCM of 32,36,48,64

Least Common Multiple (LCM) of 32,36,48,64 By Common Division

2 32, 36, 48, 64
2 16, 18, 24, 32
2 8, 9, 12, 16
2 4, 9, 6, 8
2 2, 9, 3, 4
3 1, 9, 3, 2
1, 1, 3, 2

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 3 x 1 x 1 x 3 x 2 = 576

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/576

Therefore, the GCF of Fractions 15/32,20/36,25/48,30/64 is 5/576

Least Common Multiple of 32,36,48,64 with GCF Formula

Least Common Multiple of 32,36,48,64 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 32,36,48,64 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(32,36,48,64) = 4

common factors(in case of two or more numbers have common factors) = 1536

GCF(32,36,48,64) x common factors =4 x 1536 = 6144

LCM(32,36,48,64) = ( 32 × 36 × 48 × 64 ) / 6144

LCM(32,36,48,64) = 3538944 / 6144

LCM(32,36,48,64) = 576
