Greatest Common Factor
We found the factors 55,56,24,28 . The biggest common factor number is the GCF number.
So the greatest common factor 55,56,24,28 is 1.
Lets's calculate LCM of 65,61,20,650
2 | 65, 61, 20, 650 |
5 | 65, 61, 10, 325 |
13 | 13, 61, 2, 65 |
1, 61, 2, 5 |
∴ So the LCM of the given numbers is 2 x 5 x 13 x 1 x 61 x 2 x 5 = 79300
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/79300
Therefore, the GCF of Fractions 55/65,56/61,24/20,28/650 is 1/79300
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 65,61,20,650 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,61,20,650) = 1
common factors(in case of two or more numbers have common factors) = 650
GCF(65,61,20,650) x common factors =1 x 650 = 650
LCM(65,61,20,650) = ( 65 × 61 × 20 × 650 ) / 650
LCM(65,61,20,650) = 51545000 / 650
LCM(65,61,20,650) = 79300
