Greatest Common Factor
We found the factors 25,44,22,84 . The biggest common factor number is the GCF number.
So the greatest common factor 25,44,22,84 is 1.
Lets's calculate LCM of 18,68,72,635
2 | 18, 68, 72, 635 |
2 | 9, 34, 36, 635 |
3 | 9, 17, 18, 635 |
3 | 3, 17, 6, 635 |
1, 17, 2, 635 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 1 x 17 x 2 x 635 = 777240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/777240
Therefore, the GCF of Fractions 25/18,44/68,22/72,84/635 is 1/777240
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 18,68,72,635 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,68,72,635) = 1
common factors(in case of two or more numbers have common factors) = 72
GCF(18,68,72,635) x common factors =1 x 72 = 72
LCM(18,68,72,635) = ( 18 × 68 × 72 × 635 ) / 72
LCM(18,68,72,635) = 55961280 / 72
LCM(18,68,72,635) = 777240
