1,2,4,43,86,172
Greatest Common Factor
We found the factors 18,86,172 . The biggest common factor number is the GCF number.
So the greatest common factor 18,86,172 is 2.
Lets's calculate LCM of 547,797,420
Given numbers has no common factors except 1. So, there LCM is their product i.e 183102780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/183102780
Therefore, the GCF of Fractions 18/547,86/797,172/420 is 2/183102780
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 547,797,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(547,797,420) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(547,797,420) x common factors =1 x 1 = 1
LCM(547,797,420) = ( 547 × 797 × 420 ) / 1
LCM(547,797,420) = 183102780 / 1
LCM(547,797,420) = 183102780
