Lets's calculate LCM of 754,299,983
13 | 754, 299, 983 |
58, 23, 983 |
∴ So the LCM of the given numbers is 13 x 58 x 23 x 983 = 17047186
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17047186
Therefore, the GCF of Fractions 42/754,23/299,623/983 is 1/17047186
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 754,299,983 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(754,299,983) = 1
common factors(in case of two or more numbers have common factors) = 13
GCF(754,299,983) x common factors =1 x 13 = 13
LCM(754,299,983) = ( 754 × 299 × 983 ) / 13
LCM(754,299,983) = 221613418 / 13
LCM(754,299,983) = 17047186
