Lets's calculate GCF of 524,128
2 | 524, 128 |
2 | 262, 64 |
131, 32 |
∴ So the GCF of the given numbers is 2 x 2 = 4
Now, list down the factors of 524
:1,2,4,131,262,524
Now, list down the factors of 128
:1,2,4,8,16,32,64,128
Greatest Common Factor
We found the factors 524,128 . The biggest common factor number is the GCF number.
So the greatest common factor 524,128 is 4.
Lets's calculate LCM of 460,787
Given numbers has no common factors except 1. So, there LCM is their product i.e 362020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/362020
Therefore, the GCF of Fractions 524/460,128/787 is 4/362020
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 460,787 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(460,787) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(460,787) x common factors =1 x 1 = 1
LCM(460,787) = ( 460 × 787 ) / 1
LCM(460,787) = 362020 / 1
LCM(460,787) = 362020
