Greatest Common Factor
We found the factors 86,670,247 . The biggest common factor number is the GCF number.
So the greatest common factor 86,670,247 is 1.
Lets's calculate LCM of 49,54,551
Given numbers has no common factors except 1. So, there LCM is their product i.e 1457946
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1457946
Therefore, the GCF of Fractions 86/49,670/54,247/551 is 1/1457946
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 49,54,551 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,54,551) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(49,54,551) x common factors =1 x 1 = 1
LCM(49,54,551) = ( 49 × 54 × 551 ) / 1
LCM(49,54,551) = 1457946 / 1
LCM(49,54,551) = 1457946
