Greatest Common Factor
We found the factors 869,811 . The biggest common factor number is the GCF number.
So the greatest common factor 869,811 is 1.
Lets's calculate LCM of 880,639
Given numbers has no common factors except 1. So, there LCM is their product i.e 562320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/562320
Therefore, the GCF of Fractions 869/880,811/639 is 1/562320
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 880,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(880,639) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(880,639) x common factors =1 x 1 = 1
LCM(880,639) = ( 880 × 639 ) / 1
LCM(880,639) = 562320 / 1
LCM(880,639) = 562320
