So the greatest common factor 38,34,784 is 2.
Lets's calculate LCM of 424,722,668
2 | 424, 722, 668 |
2 | 212, 361, 334 |
106, 361, 167 |
∴ So the LCM of the given numbers is 2 x 2 x 106 x 361 x 167 = 25561688
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/25561688
Therefore, the GCF of Fractions 38/424,34/722,784/668 is 2/25561688
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 424,722,668 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(424,722,668) = 2
common factors(in case of two or more numbers have common factors) = 4
GCF(424,722,668) x common factors =2 x 4 = 8
LCM(424,722,668) = ( 424 × 722 × 668 ) / 8
LCM(424,722,668) = 204493504 / 8
LCM(424,722,668) = 25561688
