Greatest Common Factor
We found the factors 3979,4280 . The biggest common factor number is the GCF number.
So the greatest common factor 3979,4280 is 1.
Lets's calculate LCM of 454,155
Given numbers has no common factors except 1. So, there LCM is their product i.e 70370
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/70370
Therefore, the GCF of Fractions 3979/454,4280/155 is 1/70370
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 454,155 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(454,155) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(454,155) x common factors =1 x 1 = 1
LCM(454,155) = ( 454 × 155 ) / 1
LCM(454,155) = 70370 / 1
LCM(454,155) = 70370
