2 | 10, 100 |
5 | 5, 50 |
1, 10 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5 = 640
Now, list down the factors of 640
:1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640
Now, list down the factors of 6400
:1,2,4,5,8,10,16,20,25,32,40,50,64,80,100,128,160,200,256,320,400,640,800,1280,1600,3200,6400
Greatest Common Factor
We found the factors 640,6400 . The biggest common factor number is the GCF number.
So the greatest common factor 640,6400 is 640.
Lets's calculate LCM of 703,938
Given numbers has no common factors except 1. So, there LCM is their product i.e 659414
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 640/659414
Therefore, the GCF of Fractions 640/703,6400/938 is 640/659414
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 703,938 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(703,938) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(703,938) x common factors =1 x 1 = 1
LCM(703,938) = ( 703 × 938 ) / 1
LCM(703,938) = 659414 / 1
LCM(703,938) = 659414
