1,2,47,94
Factors of 25
List of positive integer factors of 25 that divides 25 without a remainder.
1,5,25
Greatest Common Factor
We found the factors 96,91,94,25 . The biggest common factor number is the GCF number.
So the greatest common factor 96,91,94,25 is 1.
Lets's calculate LCM of 20,98,30,70
2 | 20, 98, 30, 70 |
5 | 10, 49, 15, 35 |
7 | 2, 49, 3, 7 |
2, 1, 3, 7 |
∴ So the LCM of the given numbers is 2 x 5 x 7 x 2 x 1 x 3 x 7 = 2940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2940
Therefore, the GCF of Fractions 96/20,91/98,94/30,25/70 is 1/2940
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 20,98,30,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,98,30,70) = 2
common factors(in case of two or more numbers have common factors) = 700
GCF(20,98,30,70) x common factors =2 x 700 = 1400
LCM(20,98,30,70) = ( 20 × 98 × 30 × 70 ) / 1400
LCM(20,98,30,70) = 4116000 / 1400
LCM(20,98,30,70) = 2940
