Lets's calculate LCM of 668,624
2 | 668, 624 |
2 | 334, 312 |
167, 156 |
∴ So the LCM of the given numbers is 2 x 2 x 167 x 156 = 104208
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/104208
Therefore, the GCF of Fractions 4280/668,1267/624 is 1/104208
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 668,624 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(668,624) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(668,624) x common factors =4 x 1 = 4
LCM(668,624) = ( 668 × 624 ) / 4
LCM(668,624) = 416832 / 4
LCM(668,624) = 104208
