Lets's calculate LCM of 61,40,28

2 61, 40, 28
2 61, 20, 14
61, 10, 7

∴ So the LCM of the given numbers is 2 x 2 x 61 x 10 x 7 = 17080

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17080

Therefore, the GCF of Fractions 93/61,85/40,217/28 is 1/17080

Least Common Multiple of 61,40,28 with GCF Formula

Least Common Multiple of 61,40,28 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 61,40,28 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(61,40,28) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(61,40,28) x common factors =1 x 4 = 4

LCM(61,40,28) = ( 61 × 40 × 28 ) / 4

LCM(61,40,28) = 68320 / 4

LCM(61,40,28) = 17080
