Lets's calculate GCF of 380,212
2 | 380, 212 |
2 | 190, 106 |
95, 53 |
∴ So the GCF of the given numbers is 2 x 2 = 4
Now, list down the factors of 380
:1,2,4,5,10,19,20,38,76,95,190,380
Now, list down the factors of 212
:1,2,4,53,106,212
Greatest Common Factor
We found the factors 380,212 . The biggest common factor number is the GCF number.
So the greatest common factor 380,212 is 4.
Lets's calculate LCM of 520,511
Given numbers has no common factors except 1. So, there LCM is their product i.e 265720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/265720
Therefore, the GCF of Fractions 380/520,212/511 is 4/265720
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 520,511 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(520,511) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(520,511) x common factors =1 x 1 = 1
LCM(520,511) = ( 520 × 511 ) / 1
LCM(520,511) = 265720 / 1
LCM(520,511) = 265720
