So the greatest common factor 49,63,210 is 7.

Lets's calculate LCM of 22,31,460

2 22, 31, 460
11, 31, 230

∴ So the LCM of the given numbers is 2 x 11 x 31 x 230 = 156860

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/156860

Therefore, the GCF of Fractions 49/22,63/31,210/460 is 7/156860

Least Common Multiple of 22,31,460 with GCF Formula

Least Common Multiple of 22,31,460 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 22,31,460 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(22,31,460) = 1

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

GCF(22,31,460) x common factors =1 x 2 = 2

LCM(22,31,460) = ( 22 × 31 × 460 ) / 2

LCM(22,31,460) = 313720 / 2

LCM(22,31,460) = 156860
