Greatest Common Factor
We found the factors 64,74,52,32 . The biggest common factor number is the GCF number.
So the greatest common factor 64,74,52,32 is 2.
Lets's calculate LCM of 20,12,98,70
2 | 20, 12, 98, 70 |
2 | 10, 6, 49, 35 |
5 | 5, 3, 49, 35 |
7 | 1, 3, 49, 7 |
1, 3, 1, 7 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 1 x 3 x 1 x 7 = 2940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2940
Therefore, the GCF of Fractions 64/20,74/12,52/98,32/70 is 2/2940
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 20,12,98,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,12,98,70) = 2
common factors(in case of two or more numbers have common factors) = 280
GCF(20,12,98,70) x common factors =2 x 280 = 560
LCM(20,12,98,70) = ( 20 × 12 × 98 × 70 ) / 560
LCM(20,12,98,70) = 1646400 / 560
LCM(20,12,98,70) = 2940
