Lets's calculate GCF of 445,420
5 | 445, 420 |
89, 84 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 445
:1,5,89,445
Now, list down the factors of 420
:1,2,3,4,5,6,7,10,12,14,15,20,21,28,30,35,42,60,70,84,105,140,210,420
Greatest Common Factor
We found the factors 445,420 . The biggest common factor number is the GCF number.
So the greatest common factor 445,420 is 5.
Lets's calculate LCM of 61,4491
Given numbers has no common factors except 1. So, there LCM is their product i.e 273951
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/273951
Therefore, the GCF of Fractions 445/61,420/4491 is 5/273951
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 61,4491 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,4491) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(61,4491) x common factors =1 x 1 = 1
LCM(61,4491) = ( 61 × 4491 ) / 1
LCM(61,4491) = 273951 / 1
LCM(61,4491) = 273951
