Greatest Common Factor
We found the factors 16,24,78,142 . The biggest common factor number is the GCF number.
So the greatest common factor 16,24,78,142 is 2.
Lets's calculate LCM of 73,11,43,72
Given numbers has no common factors except 1. So, there LCM is their product i.e 2486088
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2486088
Therefore, the GCF of Fractions 16/73,24/11,78/43,142/72 is 2/2486088
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 73,11,43,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(73,11,43,72) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(73,11,43,72) x common factors =1 x 1 = 1
LCM(73,11,43,72) = ( 73 × 11 × 43 × 72 ) / 1
LCM(73,11,43,72) = 2486088 / 1
LCM(73,11,43,72) = 2486088
