Lets's calculate LCM of 783,355,661
Given numbers has no common factors except 1. So, there LCM is their product i.e 183734865
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/183734865
Therefore, the GCF of Fractions 55/783,81/355,686/661 is 1/183734865
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 783,355,661 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(783,355,661) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(783,355,661) x common factors =1 x 1 = 1
LCM(783,355,661) = ( 783 × 355 × 661 ) / 1
LCM(783,355,661) = 183734865 / 1
LCM(783,355,661) = 183734865
