Greatest Common Factor
We found the factors 20,78,624 . The biggest common factor number is the GCF number.
So the greatest common factor 20,78,624 is 2.
Lets's calculate LCM of 24,80,92
2 | 24, 80, 92 |
2 | 12, 40, 46 |
2 | 6, 20, 23 |
3, 10, 23 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 10 x 23 = 5520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/5520
Therefore, the GCF of Fractions 20/24,78/80,624/92 is 2/5520
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 24,80,92 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(24,80,92) = 4
common factors(in case of two or more numbers have common factors) = 8
GCF(24,80,92) x common factors =4 x 8 = 32
LCM(24,80,92) = ( 24 × 80 × 92 ) / 32
LCM(24,80,92) = 176640 / 32
LCM(24,80,92) = 5520
