Lets's calculate LCM of 698,356
2 | 698, 356 |
349, 178 |
∴ So the LCM of the given numbers is 2 x 349 x 178 = 124244
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 39/124244
Therefore, the GCF of Fractions 507/698,8970/356 is 39/124244
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 698,356 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(698,356) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(698,356) x common factors =2 x 1 = 2
LCM(698,356) = ( 698 × 356 ) / 2
LCM(698,356) = 248488 / 2
LCM(698,356) = 124244
