Lets's calculate LCM of 956,668
2 | 956, 668 |
2 | 478, 334 |
239, 167 |
∴ So the LCM of the given numbers is 2 x 2 x 239 x 167 = 159652
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/159652
Therefore, the GCF of Fractions 981/956,479/668 is 1/159652
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 956,668 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(956,668) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(956,668) x common factors =4 x 1 = 4
LCM(956,668) = ( 956 × 668 ) / 4
LCM(956,668) = 638608 / 4
LCM(956,668) = 159652
