Lets's calculate LCM of 49,44,69,61

Given numbers has no common factors except 1. So, there LCM is their product i.e 9074604

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9074604

Therefore, the GCF of Fractions 71/49,83/44,30/69,17/61 is 1/9074604

Least Common Multiple of 49,44,69,61 with GCF Formula

Least Common Multiple of 49,44,69,61 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 49,44,69,61 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(49,44,69,61) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(49,44,69,61) x common factors =1 x 1 = 1

LCM(49,44,69,61) = ( 49 × 44 × 69 × 61 ) / 1

LCM(49,44,69,61) = 9074604 / 1

LCM(49,44,69,61) = 9074604
