Lets's calculate GCF of 637,728
7 | 637, 728 |
13 | 91, 104 |
7, 8 |
∴ So the GCF of the given numbers is 7 x 13 = 91
Now, list down the factors of 637
:1,7,13,49,91,637
Now, list down the factors of 728
:1,2,4,7,8,13,14,26,28,52,56,91,104,182,364,728
Greatest Common Factor
We found the factors 637,728 . The biggest common factor number is the GCF number.
So the greatest common factor 637,728 is 91.
Lets's calculate LCM of 63,991
Given numbers has no common factors except 1. So, there LCM is their product i.e 62433
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 91/62433
Therefore, the GCF of Fractions 637/63,728/991 is 91/62433
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 63,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(63,991) x common factors =1 x 1 = 1
LCM(63,991) = ( 63 × 991 ) / 1
LCM(63,991) = 62433 / 1
LCM(63,991) = 62433
