So the greatest common factor 76,69,78,79 is 1.

Lets's calculate LCM of 61,78,83,800

2 61, 78, 83, 800
61, 39, 83, 400

∴ So the LCM of the given numbers is 2 x 61 x 39 x 83 x 400 = 157965600

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/157965600

Therefore, the GCF of Fractions 76/61,69/78,78/83,79/800 is 1/157965600

Least Common Multiple of 61,78,83,800 with GCF Formula

Least Common Multiple of 61,78,83,800 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 61,78,83,800 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(61,78,83,800) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(61,78,83,800) x common factors =1 x 2 = 2

LCM(61,78,83,800) = ( 61 × 78 × 83 × 800 ) / 2

LCM(61,78,83,800) = 315931200 / 2

LCM(61,78,83,800) = 157965600
