So the greatest common factor 669,255 is 3.
Lets's calculate LCM of 702,370
2 | 702, 370 |
351, 185 |
∴ So the LCM of the given numbers is 2 x 351 x 185 = 129870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/129870
Therefore, the GCF of Fractions 669/702,255/370 is 3/129870
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 702,370 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(702,370) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(702,370) x common factors =2 x 1 = 2
LCM(702,370) = ( 702 × 370 ) / 2
LCM(702,370) = 259740 / 2
LCM(702,370) = 129870
