Greatest Common Factor
We found the factors 38,56,74,26 . The biggest common factor number is the GCF number.
So the greatest common factor 38,56,74,26 is 2.
Lets's calculate LCM of 65,78,50,484
2 | 65, 78, 50, 484 |
5 | 65, 39, 25, 242 |
13 | 13, 39, 5, 242 |
1, 3, 5, 242 |
∴ So the LCM of the given numbers is 2 x 5 x 13 x 1 x 3 x 5 x 242 = 471900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/471900
Therefore, the GCF of Fractions 38/65,56/78,74/50,26/484 is 2/471900
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 65,78,50,484 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,78,50,484) = 1
common factors(in case of two or more numbers have common factors) = 260
GCF(65,78,50,484) x common factors =1 x 260 = 260
LCM(65,78,50,484) = ( 65 × 78 × 50 × 484 ) / 260
LCM(65,78,50,484) = 122694000 / 260
LCM(65,78,50,484) = 471900
