1,2,5,7,10,14,35,49,70,98,245,490
Greatest Common Factor
We found the factors 68,56,490 . The biggest common factor number is the GCF number.
So the greatest common factor 68,56,490 is 2.
Lets's calculate LCM of 29,74,715
Given numbers has no common factors except 1. So, there LCM is their product i.e 1534390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1534390
Therefore, the GCF of Fractions 68/29,56/74,490/715 is 2/1534390
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 29,74,715 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(29,74,715) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(29,74,715) x common factors =1 x 1 = 1
LCM(29,74,715) = ( 29 × 74 × 715 ) / 1
LCM(29,74,715) = 1534390 / 1
LCM(29,74,715) = 1534390
Here are some samples of GCF of Fractions calculations.
