List of positive integer factors of 712 that divides 712 without a remainder.
1,2,4,8,89,178,356,712
Greatest Common Factor
We found the factors 71,90,712 . The biggest common factor number is the GCF number.
So the greatest common factor 71,90,712 is 1.
Lets's calculate LCM of 79,17,870
Given numbers has no common factors except 1. So, there LCM is their product i.e 1168410
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1168410
Therefore, the GCF of Fractions 71/79,90/17,712/870 is 1/1168410
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 79,17,870 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,17,870) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,17,870) x common factors =1 x 1 = 1
LCM(79,17,870) = ( 79 × 17 × 870 ) / 1
LCM(79,17,870) = 1168410 / 1
LCM(79,17,870) = 1168410
Here are some samples of GCF of Fractions calculations.
