We found the factors 40,80,792 . The biggest common factor number is the GCF number.
So the greatest common factor 40,80,792 is 8.
Lets's calculate LCM of 490,379,213
Given numbers has no common factors except 1. So, there LCM is their product i.e 39556230
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/39556230
Therefore, the GCF of Fractions 40/490,80/379,792/213 is 8/39556230
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 490,379,213 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(490,379,213) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(490,379,213) x common factors =1 x 1 = 1
LCM(490,379,213) = ( 490 × 379 × 213 ) / 1
LCM(490,379,213) = 39556230 / 1
LCM(490,379,213) = 39556230
