Greatest Common Factor

We found the factors 30,400,625 . The biggest common factor number is the GCF number.
So the greatest common factor 30,400,625 is 5.


Lets's calculate LCM of 18,90,148

2 18, 90, 148
3 9, 45, 74
3 3, 15, 74
1, 5, 74

∴ So the LCM of the given numbers is 2 x 3 x 3 x 1 x 5 x 74 = 6660

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/6660

Therefore, the GCF of Fractions 30/18,400/90,625/148 is 5/6660

Least Common Multiple of 18,90,148 with GCF Formula

Least Common Multiple of 18,90,148 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 18,90,148 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(18,90,148) = 2

common factors(in case of two or more numbers have common factors) = 18

GCF(18,90,148) x common factors =2 x 18 = 36

LCM(18,90,148) = ( 18 × 90 × 148 ) / 36

LCM(18,90,148) = 239760 / 36

LCM(18,90,148) = 6660
