Greatest Common Factor
We found the factors 630,549 . The biggest common factor number is the GCF number.
So the greatest common factor 630,549 is 9.
Lets's calculate LCM of 86,679
Given numbers has no common factors except 1. So, there LCM is their product i.e 58394
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/58394
Therefore, the GCF of Fractions 630/86,549/679 is 9/58394
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 86,679 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,679) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(86,679) x common factors =1 x 1 = 1
LCM(86,679) = ( 86 × 679 ) / 1
LCM(86,679) = 58394 / 1
LCM(86,679) = 58394
