The HCF of 220,640 is 20.
Lets's calculate GCF of 220,640
2 | 220, 640 |
2 | 110, 320 |
5 | 55, 160 |
11, 32 |
∴ So the GCF of the given numbers is 2 x 2 x 5 = 20
Now, list down the factors of 220
:1,2,4,5,10,11,20,22,44,55,110,220
Now, list down the factors of 640
:1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640
Greatest Common Factor
We found the factors 220,640 . The biggest common factor number is the GCF number.
So the greatest common factor 220,640 is 20.
Lets's calculate LCM of 451,500
Given numbers has no common factors except 1. So, there LCM is their product i.e 225500
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/225500
Therefore, the GCF of Fractions 220/451,640/500 is 20/225500
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 451,500 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(451,500) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(451,500) x common factors =1 x 1 = 1
LCM(451,500) = ( 451 × 500 ) / 1
LCM(451,500) = 225500 / 1
LCM(451,500) = 225500
