Lets's calculate LCM of 84,674
2 | 84, 674 |
42, 337 |
∴ So the LCM of the given numbers is 2 x 42 x 337 = 28308
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 92/28308
Therefore, the GCF of Fractions 644/84,736/674 is 92/28308
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 84,674 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,674) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(84,674) x common factors =2 x 1 = 2
LCM(84,674) = ( 84 × 674 ) / 2
LCM(84,674) = 56616 / 2
LCM(84,674) = 28308
