Greatest Common Factor

We found the factors 280,407 . The biggest common factor number is the GCF number.
So the greatest common factor 280,407 is 1.

Lets's calculate LCM of 70,2750

2 70, 2750
5 35, 1375
7, 275

∴ So the LCM of the given numbers is 2 x 5 x 7 x 275 = 19250

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19250

Therefore, the GCF of Fractions 280/70,407/2750 is 1/19250

Least Common Multiple of 70,2750 with GCF Formula

Least Common Multiple of 70,2750 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 70,2750 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,2750) = 10

common factors(in case of two or more numbers have common factors) = 1

GCF(70,2750) x common factors =10 x 1 = 10

LCM(70,2750) = ( 70 × 2750 ) / 10

LCM(70,2750) = 192500 / 10

LCM(70,2750) = 19250
