Greatest Common Factor

We found the factors 34,10,72,85 . The biggest common factor number is the GCF number.
So the greatest common factor 34,10,72,85 is 1.

Lets's calculate LCM of 98,86,20,57

2 98, 86, 20, 57
49, 43, 10, 57

∴ So the LCM of the given numbers is 2 x 49 x 43 x 10 x 57 = 2401980

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2401980

Therefore, the GCF of Fractions 34/98,10/86,72/20,85/57 is 1/2401980

Least Common Multiple of 98,86,20,57 with GCF Formula

Least Common Multiple of 98,86,20,57 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 98,86,20,57 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(98,86,20,57) = 1

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

GCF(98,86,20,57) x common factors =1 x 4 = 4

LCM(98,86,20,57) = ( 98 × 86 × 20 × 57 ) / 4

LCM(98,86,20,57) = 9607920 / 4

LCM(98,86,20,57) = 2401980
