Lets's calculate LCM of 86,58,58,28

2 86, 58, 58, 28
29 43, 29, 29, 14
43, 1, 1, 14

∴ So the LCM of the given numbers is 2 x 29 x 43 x 1 x 1 x 14 = 34916

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/34916

Therefore, the GCF of Fractions 65/86,25/58,90/58,66/28 is 1/34916

Least Common Multiple of 86,58,58,28 with GCF Formula

Least Common Multiple of 86,58,58,28 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 86,58,58,28 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(86,58,58,28) = 2

common factors(in case of two or more numbers have common factors) = 116

GCF(86,58,58,28) x common factors =2 x 116 = 232

LCM(86,58,58,28) = ( 86 × 58 × 58 × 28 ) / 232

LCM(86,58,58,28) = 8100512 / 232

LCM(86,58,58,28) = 34916
