Lets's calculate LCM of 702,660
2 | 702, 660 |
3 | 351, 330 |
117, 110 |
∴ So the LCM of the given numbers is 2 x 3 x 117 x 110 = 77220
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/77220
Therefore, the GCF of Fractions 749/702,490/660 is 7/77220
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 702,660 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(702,660) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(702,660) x common factors =6 x 1 = 6
LCM(702,660) = ( 702 × 660 ) / 6
LCM(702,660) = 463320 / 6
LCM(702,660) = 77220
