1,2,4,5,10,20
Factors of 22
List of positive integer factors of 22 that divides 22 without a remainder.
1,2,11,22
Factors of 747
List of positive integer factors of 747 that divides 747 without a remainder.
1,3,9,83,249,747
Greatest Common Factor
We found the factors 18,20,22,747 . The biggest common factor number is the GCF number.
So the greatest common factor 18,20,22,747 is 1.
Lets's calculate LCM of 67,58,79,38
2 | 67, 58, 79, 38 |
67, 29, 79, 19 |
∴ So the LCM of the given numbers is 2 x 67 x 29 x 79 x 19 = 5832886
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5832886
Therefore, the GCF of Fractions 18/67,20/58,22/79,747/38 is 1/5832886
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 67,58,79,38 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,58,79,38) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(67,58,79,38) x common factors =1 x 2 = 2
LCM(67,58,79,38) = ( 67 × 58 × 79 × 38 ) / 2
LCM(67,58,79,38) = 11665772 / 2
LCM(67,58,79,38) = 5832886
