Lets's calculate LCM of 709,880
Given numbers has no common factors except 1. So, there LCM is their product i.e 623920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/623920
Therefore, the GCF of Fractions 877/709,420/880 is 1/623920
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 709,880 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(709,880) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(709,880) x common factors =1 x 1 = 1
LCM(709,880) = ( 709 × 880 ) / 1
LCM(709,880) = 623920 / 1
LCM(709,880) = 623920
