So the greatest common factor 40,57,789 is 1.
Lets's calculate LCM of 854,429,224
2 | 854, 429, 224 |
7 | 427, 429, 112 |
61, 429, 16 |
∴ So the LCM of the given numbers is 2 x 7 x 61 x 429 x 16 = 5861856
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5861856
Therefore, the GCF of Fractions 40/854,57/429,789/224 is 1/5861856
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 854,429,224 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(854,429,224) = 1
common factors(in case of two or more numbers have common factors) = 14
GCF(854,429,224) x common factors =1 x 14 = 14
LCM(854,429,224) = ( 854 × 429 × 224 ) / 14
LCM(854,429,224) = 82065984 / 14
LCM(854,429,224) = 5861856
