Greatest Common Factor
We found the factors 30,609,667 . The biggest common factor number is the GCF number.
So the greatest common factor 30,609,667 is 1.
Lets's calculate LCM of 57,67,121
Given numbers has no common factors except 1. So, there LCM is their product i.e 462099
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/462099
Therefore, the GCF of Fractions 30/57,609/67,667/121 is 1/462099
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 57,67,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,67,121) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(57,67,121) x common factors =1 x 1 = 1
LCM(57,67,121) = ( 57 × 67 × 121 ) / 1
LCM(57,67,121) = 462099 / 1
LCM(57,67,121) = 462099
