Greatest Common Factor
We found the factors 12,940,128 . The biggest common factor number is the GCF number.
So the greatest common factor 12,940,128 is 4.
Lets's calculate LCM of 601,440,391
Given numbers has no common factors except 1. So, there LCM is their product i.e 103396040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/103396040
Therefore, the GCF of Fractions 12/601,940/440,128/391 is 4/103396040
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 601,440,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(601,440,391) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(601,440,391) x common factors =1 x 1 = 1
LCM(601,440,391) = ( 601 × 440 × 391 ) / 1
LCM(601,440,391) = 103396040 / 1
LCM(601,440,391) = 103396040
