GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 28,80,262
Greatest Common Factor of Numerators i.e. GCF of 28,80,262 is 2 .
LCM of Denominators means LCM of 70,77,66 as per the given fractions.
LCM of 70,77,66 is 2310 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 28,80,262
2 | 28, 80, 262 |
14, 40, 131 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 28
List of positive integer factors of 28 that divides 28 without a remainder.
1,2,4,7,14,28
Factors of 80
List of positive integer factors of 80 that divides 80 without a remainder.
1,2,4,5,8,10,16,20,40,80
Factors of 262
List of positive integer factors of 262 that divides 262 without a remainder.
1,2,131,262
Greatest Common Factor
We found the factors 28,80,262 . The biggest common factor number is the GCF number.
So the greatest common factor 28,80,262 is 2.
Lets's calculate LCM of 70,77,66
2 | 70, 77, 66 |
7 | 35, 77, 33 |
11 | 5, 11, 33 |
5, 1, 3 |
∴ So the LCM of the given numbers is 2 x 7 x 11 x 5 x 1 x 3 = 2310
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2310
Therefore, the GCF of Fractions 28/70,80/77,262/66 is 2/2310
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 70,77,66 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,77,66) = 1
common factors(in case of two or more numbers have common factors) = 154
GCF(70,77,66) x common factors =1 x 154 = 154
LCM(70,77,66) = ( 70 × 77 × 66 ) / 154
LCM(70,77,66) = 355740 / 154
LCM(70,77,66) = 2310
