List of positive integer factors of 23 that divides 23 without a remainder.
1,23
Greatest Common Factor
We found the factors 56,27,21,23 . The biggest common factor number is the GCF number.
So the greatest common factor 56,27,21,23 is 1.
Lets's calculate LCM of 24,92,74,24
2 | 24, 92, 74, 24 |
2 | 12, 46, 37, 12 |
2 | 6, 23, 37, 6 |
3 | 3, 23, 37, 3 |
1, 23, 37, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 1 x 23 x 37 x 1 = 20424
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20424
Therefore, the GCF of Fractions 56/24,27/92,21/74,23/24 is 1/20424
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 24,92,74,24 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(24,92,74,24) = 2
common factors(in case of two or more numbers have common factors) = 96
GCF(24,92,74,24) x common factors =2 x 96 = 192
LCM(24,92,74,24) = ( 24 × 92 × 74 × 24 ) / 192
LCM(24,92,74,24) = 3921408 / 192
LCM(24,92,74,24) = 20424
