31 | 651, 620 |
21, 20 |
∴ So the GCF of the given numbers is 31 = 31
Now, list down the factors of 651
:1,3,7,21,31,93,217,651
Now, list down the factors of 620
:1,2,4,5,10,20,31,62,124,155,310,620
Greatest Common Factor
We found the factors 651,620 . The biggest common factor number is the GCF number.
So the greatest common factor 651,620 is 31.
Lets's calculate LCM of 45,297
3 | 45, 297 |
3 | 15, 99 |
5, 33 |
∴ So the LCM of the given numbers is 3 x 3 x 5 x 33 = 1485
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 31/1485
Therefore, the GCF of Fractions 651/45,620/297 is 31/1485
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 45,297 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,297) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(45,297) x common factors =9 x 1 = 9
LCM(45,297) = ( 45 × 297 ) / 9
LCM(45,297) = 13365 / 9
LCM(45,297) = 1485
