Greatest Common Factor
We found the factors 781,485,665 . The biggest common factor number is the GCF number.
So the greatest common factor 781,485,665 is 1.
Lets's calculate LCM of 82,49,465
Given numbers has no common factors except 1. So, there LCM is their product i.e 1868370
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1868370
Therefore, the GCF of Fractions 781/82,485/49,665/465 is 1/1868370
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 82,49,465 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(82,49,465) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(82,49,465) x common factors =1 x 1 = 1
LCM(82,49,465) = ( 82 × 49 × 465 ) / 1
LCM(82,49,465) = 1868370 / 1
LCM(82,49,465) = 1868370
