Lets's calculate LCM of 762,382
2 | 762, 382 |
381, 191 |
∴ So the LCM of the given numbers is 2 x 381 x 191 = 145542
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/145542
Therefore, the GCF of Fractions 245/762,6170/382 is 5/145542
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 762,382 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(762,382) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(762,382) x common factors =2 x 1 = 2
LCM(762,382) = ( 762 × 382 ) / 2
LCM(762,382) = 291084 / 2
LCM(762,382) = 145542
