Greatest Common Factor
We found the factors 803,823,740 . The biggest common factor number is the GCF number.
So the greatest common factor 803,823,740 is 1.
Lets's calculate LCM of 79,39,128
Given numbers has no common factors except 1. So, there LCM is their product i.e 394368
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/394368
Therefore, the GCF of Fractions 803/79,823/39,740/128 is 1/394368
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 79,39,128 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,39,128) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,39,128) x common factors =1 x 1 = 1
LCM(79,39,128) = ( 79 × 39 × 128 ) / 1
LCM(79,39,128) = 394368 / 1
LCM(79,39,128) = 394368
