Lets's calculate GCF of 427,280
7 | 427, 280 |
61, 40 |
∴ So the GCF of the given numbers is 7 = 7
Now, list down the factors of 427
:1,7,61,427
Now, list down the factors of 280
:1,2,4,5,7,8,10,14,20,28,35,40,56,70,140,280
Greatest Common Factor
We found the factors 427,280 . The biggest common factor number is the GCF number.
So the greatest common factor 427,280 is 7.
Lets's calculate LCM of 89,807
Given numbers has no common factors except 1. So, there LCM is their product i.e 71823
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/71823
Therefore, the GCF of Fractions 427/89,280/807 is 7/71823
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 89,807 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,807) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,807) x common factors =1 x 1 = 1
LCM(89,807) = ( 89 × 807 ) / 1
LCM(89,807) = 71823 / 1
LCM(89,807) = 71823
