Greatest Common Factor

We found the factors 72,20,846 . The biggest common factor number is the GCF number.
So the greatest common factor 72,20,846 is 2.

Lets's calculate LCM of 68,17,74

2 68, 17, 74
17 34, 17, 37
2, 1, 37

∴ So the LCM of the given numbers is 2 x 17 x 2 x 1 x 37 = 2516

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2516

Therefore, the GCF of Fractions 72/68,20/17,846/74 is 2/2516

Least Common Multiple of 68,17,74 with GCF Formula

Least Common Multiple of 68,17,74 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 68,17,74 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(68,17,74) = 1

common factors(in case of two or more numbers have common factors) = 34

GCF(68,17,74) x common factors =1 x 34 = 34

LCM(68,17,74) = ( 68 × 17 × 74 ) / 34

LCM(68,17,74) = 85544 / 34

LCM(68,17,74) = 2516
