1,2,4,5,8,10,16,17,20,32,34,40,68,80,85,136,160,170,272,340,544,680,1360,2720
Factors of 1020
List of positive integer factors of 1020 that divides 1020 without a remainder.
1,2,3,4,5,6,10,12,15,17,20,30,34,51,60,68,85,102,170,204,255,340,510,1020
Greatest Common Factor
We found the factors 2720,1020 . The biggest common factor number is the GCF number.
So the greatest common factor 2720,1020 is 340.
Lets's calculate LCM of 98,530
2 | 98, 530 |
49, 265 |
∴ So the LCM of the given numbers is 2 x 49 x 265 = 25970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 340/25970
Therefore, the GCF of Fractions 2720/98,1020/530 is 340/25970
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 98,530 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(98,530) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(98,530) x common factors =2 x 1 = 2
LCM(98,530) = ( 98 × 530 ) / 2
LCM(98,530) = 51940 / 2
LCM(98,530) = 25970
