Lets's calculate GCF of 651,945
3 | 651, 945 |
7 | 217, 315 |
31, 45 |
∴ So the GCF of the given numbers is 3 x 7 = 21
Now, list down the factors of 651
:1,3,7,21,31,93,217,651
Now, list down the factors of 945
:1,3,5,7,9,15,21,27,35,45,63,105,135,189,315,945
Greatest Common Factor
We found the factors 651,945 . The biggest common factor number is the GCF number.
So the greatest common factor 651,945 is 21.
Lets's calculate LCM of 22,465
Given numbers has no common factors except 1. So, there LCM is their product i.e 10230
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/10230
Therefore, the GCF of Fractions 651/22,945/465 is 21/10230
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 22,465 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(22,465) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(22,465) x common factors =1 x 1 = 1
LCM(22,465) = ( 22 × 465 ) / 1
LCM(22,465) = 10230 / 1
LCM(22,465) = 10230
