Lets's calculate LCM of 924,770
2 | 924, 770 |
7 | 462, 385 |
11 | 66, 55 |
6, 5 |
∴ So the LCM of the given numbers is 2 x 7 x 11 x 6 x 5 = 4620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/4620
Therefore, the GCF of Fractions 825/924,820/770 is 5/4620
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 924,770 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(924,770) = 154
common factors(in case of two or more numbers have common factors) = 1
GCF(924,770) x common factors =154 x 1 = 154
LCM(924,770) = ( 924 × 770 ) / 154
LCM(924,770) = 711480 / 154
LCM(924,770) = 4620
