:1,2,4,8,73,146,292,584
Greatest Common Factor
We found the factors 19,245,584 . The biggest common factor number is the GCF number.
So the greatest common factor 19,245,584 is 1.
Lets's calculate LCM of 42,21,742
2 | 42, 21, 742 |
3 | 21, 21, 371 |
7 | 7, 7, 371 |
1, 1, 53 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 1 x 53 = 2226
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2226
Therefore, the GCF of Fractions 19/42,245/21,584/742 is 1/2226
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 42,21,742 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,21,742) = 7
common factors(in case of two or more numbers have common factors) = 42
GCF(42,21,742) x common factors =7 x 42 = 294
LCM(42,21,742) = ( 42 × 21 × 742 ) / 294
LCM(42,21,742) = 654444 / 294
LCM(42,21,742) = 2226
