LCM of 95,42,819 is 155610 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 56,39,670
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 56
List of positive integer factors of 56 that divides 56 without a remainder.
1,2,4,7,8,14,28,56
Factors of 39
List of positive integer factors of 39 that divides 39 without a remainder.
1,3,13,39
Factors of 670
List of positive integer factors of 670 that divides 670 without a remainder.
1,2,5,10,67,134,335,670
Greatest Common Factor
We found the factors 56,39,670 . The biggest common factor number is the GCF number.
So the greatest common factor 56,39,670 is 1.
Lets's calculate LCM of 95,42,819
3 | 95, 42, 819 |
7 | 95, 14, 273 |
95, 2, 39 |
∴ So the LCM of the given numbers is 3 x 7 x 95 x 2 x 39 = 155610
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/155610
Therefore, the GCF of Fractions 56/95,39/42,670/819 is 1/155610
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 95,42,819 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(95,42,819) = 1
common factors(in case of two or more numbers have common factors) = 21
GCF(95,42,819) x common factors =1 x 21 = 21
LCM(95,42,819) = ( 95 × 42 × 819 ) / 21
LCM(95,42,819) = 3267810 / 21
LCM(95,42,819) = 155610
