So the greatest common factor 86,72,90,17 is 1.

Lets's calculate LCM of 88,21,19,260

2 88, 21, 19, 260
2 44, 21, 19, 130
22, 21, 19, 65

∴ So the LCM of the given numbers is 2 x 2 x 22 x 21 x 19 x 65 = 2282280

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2282280

Therefore, the GCF of Fractions 86/88,72/21,90/19,17/260 is 1/2282280

Least Common Multiple of 88,21,19,260 with GCF Formula

Least Common Multiple of 88,21,19,260 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 88,21,19,260 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(88,21,19,260) = 1

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

GCF(88,21,19,260) x common factors =1 x 4 = 4

LCM(88,21,19,260) = ( 88 × 21 × 19 × 260 ) / 4

LCM(88,21,19,260) = 9129120 / 4

LCM(88,21,19,260) = 2282280
