Lets's calculate LCM of 838,506
2 | 838, 506 |
419, 253 |
∴ So the LCM of the given numbers is 2 x 419 x 253 = 212014
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/212014
Therefore, the GCF of Fractions 7970/838,9906/506 is 2/212014
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 838,506 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(838,506) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(838,506) x common factors =2 x 1 = 2
LCM(838,506) = ( 838 × 506 ) / 2
LCM(838,506) = 424028 / 2
LCM(838,506) = 212014
