Lets's calculate LCM of 638,1604
2 | 638, 1604 |
319, 802 |
∴ So the LCM of the given numbers is 2 x 319 x 802 = 511676
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/511676
Therefore, the GCF of Fractions 4257/638,3174/1604 is 3/511676
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 638,1604 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(638,1604) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(638,1604) x common factors =2 x 1 = 2
LCM(638,1604) = ( 638 × 1604 ) / 2
LCM(638,1604) = 1023352 / 2
LCM(638,1604) = 511676
