:1,2,5,10,67,134,335,670
Greatest Common Factor
We found the factors 660,670 . The biggest common factor number is the GCF number.
So the greatest common factor 660,670 is 10.
Lets's calculate LCM of 634,393
Given numbers has no common factors except 1. So, there LCM is their product i.e 249162
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/249162
Therefore, the GCF of Fractions 660/634,670/393 is 10/249162
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 634,393 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(634,393) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(634,393) x common factors =1 x 1 = 1
LCM(634,393) = ( 634 × 393 ) / 1
LCM(634,393) = 249162 / 1
LCM(634,393) = 249162
