Lets's calculate GCF of 570,810
2 | 570, 810 |
3 | 285, 405 |
5 | 95, 135 |
19, 27 |
∴ So the GCF of the given numbers is 2 x 3 x 5 = 30
Now, list down the factors of 570
:1,2,3,5,6,10,15,19,30,38,57,95,114,190,285,570
Now, list down the factors of 810
:1,2,3,5,6,9,10,15,18,27,30,45,54,81,90,135,162,270,405,810
Greatest Common Factor
We found the factors 570,810 . The biggest common factor number is the GCF number.
So the greatest common factor 570,810 is 30.
Lets's calculate LCM of 51,428
Given numbers has no common factors except 1. So, there LCM is their product i.e 21828
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 30/21828
Therefore, the GCF of Fractions 570/51,810/428 is 30/21828
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 51,428 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,428) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(51,428) x common factors =1 x 1 = 1
LCM(51,428) = ( 51 × 428 ) / 1
LCM(51,428) = 21828 / 1
LCM(51,428) = 21828
