3 | 660, 111 |
220, 37 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 660
:1,2,3,4,5,6,10,11,12,15,20,22,30,33,44,55,60,66,110,132,165,220,330,660
Now, list down the factors of 111
:1,3,37,111
Greatest Common Factor
We found the factors 660,111 . The biggest common factor number is the GCF number.
So the greatest common factor 660,111 is 3.
Lets's calculate LCM of 901,638
Given numbers has no common factors except 1. So, there LCM is their product i.e 574838
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/574838
Therefore, the GCF of Fractions 660/901,111/638 is 3/574838
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 901,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(901,638) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(901,638) x common factors =1 x 1 = 1
LCM(901,638) = ( 901 × 638 ) / 1
LCM(901,638) = 574838 / 1
LCM(901,638) = 574838
