Greatest Common Factor
We found the factors 55,16,686 . The biggest common factor number is the GCF number.
So the greatest common factor 55,16,686 is 1.
Lets's calculate LCM of 67,42,473
Given numbers has no common factors except 1. So, there LCM is their product i.e 1331022
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1331022
Therefore, the GCF of Fractions 55/67,16/42,686/473 is 1/1331022
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 67,42,473 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,42,473) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(67,42,473) x common factors =1 x 1 = 1
LCM(67,42,473) = ( 67 × 42 × 473 ) / 1
LCM(67,42,473) = 1331022 / 1
LCM(67,42,473) = 1331022
