Lets's calculate LCM of 266,861
7 | 266, 861 |
38, 123 |
∴ So the LCM of the given numbers is 7 x 38 x 123 = 32718
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/32718
Therefore, the GCF of Fractions 620/266,622/861 is 2/32718
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 266,861 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(266,861) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(266,861) x common factors =7 x 1 = 7
LCM(266,861) = ( 266 × 861 ) / 7
LCM(266,861) = 229026 / 7
LCM(266,861) = 32718
