So the greatest common factor 99,21,29,62,642,76,93,624,77,92 is 1.


Lets's calculate LCM of 9,7,6,4,3,6,5,8,9,2

2 9, 7, 6, 4, 3, 6, 5, 8, 9, 2
2 9, 7, 3, 2, 3, 3, 5, 4, 9, 1
3 9, 7, 3, 1, 3, 3, 5, 2, 9, 1
3 1, 7, 1, 1, 1, 3, 5, 2, 3, 1
1, 7, 1, 1, 1, 1, 5, 2, 1, 1

∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 1 x 7 x 1 x 1 x 1 x 1 x 5 x 2 x 1 x 1 = 2520

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2520

Therefore, the GCF of Fractions 99/9,21/7,29/6,62/4,642/3,76/6,93/5,624/8,77/9,92/2 is 1/2520

Least Common Multiple of 9,7,6,4,3,6,5,8,9,2 with GCF Formula

Least Common Multiple of 9,7,6,4,3,6,5,8,9,2 with GCF Formula

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 9,7,6,4,3,6,5,8,9,2 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(9,7,6,4,3,6,5,8,9,2) = 1

common factors(in case of two or more numbers have common factors) = 7776

GCF(9,7,6,4,3,6,5,8,9,2) x common factors =1 x 7776 = 7776

LCM(9,7,6,4,3,6,5,8,9,2) = ( 9 × 7 × 6 × 4 × 3 × 6 × 5 × 8 × 9 × 2 ) / 7776

LCM(9,7,6,4,3,6,5,8,9,2) = 19595520 / 7776

LCM(9,7,6,4,3,6,5,8,9,2) = 2520
