Lets's calculate LCM of 28,26,715
2 | 28, 26, 715 |
13 | 14, 13, 715 |
14, 1, 55 |
∴ So the LCM of the given numbers is 2 x 13 x 14 x 1 x 55 = 20020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/20020
Therefore, the GCF of Fractions 40/28,260/26,620/715 is 20/20020
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 28,26,715 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,26,715) = 1
common factors(in case of two or more numbers have common factors) = 26
GCF(28,26,715) x common factors =1 x 26 = 26
LCM(28,26,715) = ( 28 × 26 × 715 ) / 26
LCM(28,26,715) = 520520 / 26
LCM(28,26,715) = 20020
