The factors of 7 are 1, 7
The factors of 21 are 1, 3, 7, 21
The factors of 77 are 1, 7, 11, 77
The HCF of 7,21,77 is 7.
Lets's calculate GCF of 7,21,77
7 | 7, 21, 77 |
1, 3, 11 |
∴ So the GCF of the given numbers is 7 = 7
Now, list down the factors of 7
:1,7
Now, list down the factors of 21
:1,3,7,21
Now, list down the factors of 77
:1,7,11,77
Greatest Common Factor
We found the factors 7,21,77 . The biggest common factor number is the GCF number.
So the greatest common factor 7,21,77 is 7.
Lets's calculate LCM of 16,827,421
Given numbers has no common factors except 1. So, there LCM is their product i.e 5570672
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/5570672
Therefore, the GCF of Fractions 7/16,21/827,77/421 is 7/5570672
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 16,827,421 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,827,421) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(16,827,421) x common factors =1 x 1 = 1
LCM(16,827,421) = ( 16 × 827 × 421 ) / 1
LCM(16,827,421) = 5570672 / 1
LCM(16,827,421) = 5570672
