Lets's calculate LCM of 79,19,561,865
Given numbers has no common factors except 1. So, there LCM is their product i.e 728382765
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/728382765
Therefore, the GCF of Fractions 1/79,76/19,68/561,369/865 is 1/728382765
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 79,19,561,865 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,19,561,865) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,19,561,865) x common factors =1 x 1 = 1
LCM(79,19,561,865) = ( 79 × 19 × 561 × 865 ) / 1
LCM(79,19,561,865) = 728382765 / 1
LCM(79,19,561,865) = 728382765
