Lets's calculate LCM of 870,132
2 | 870, 132 |
3 | 435, 66 |
145, 22 |
∴ So the LCM of the given numbers is 2 x 3 x 145 x 22 = 19140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/19140
Therefore, the GCF of Fractions 822/870,279/132 is 3/19140
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 870,132 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(870,132) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(870,132) x common factors =6 x 1 = 6
LCM(870,132) = ( 870 × 132 ) / 6
LCM(870,132) = 114840 / 6
LCM(870,132) = 19140
