Greatest Common Factor
We found the factors 455,3220 . The biggest common factor number is the GCF number.
So the greatest common factor 455,3220 is 35.
Lets's calculate LCM of 67,615
Given numbers has no common factors except 1. So, there LCM is their product i.e 41205
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 35/41205
Therefore, the GCF of Fractions 455/67,3220/615 is 35/41205
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 67,615 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,615) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(67,615) x common factors =1 x 1 = 1
LCM(67,615) = ( 67 × 615 ) / 1
LCM(67,615) = 41205 / 1
LCM(67,615) = 41205
