Greatest Common Factor
We found the factors 58,22,87,56 . The biggest common factor number is the GCF number.
So the greatest common factor 58,22,87,56 is 1.
Lets's calculate LCM of 70,45,18,70
2 | 70, 45, 18, 70 |
3 | 35, 45, 9, 35 |
3 | 35, 15, 3, 35 |
5 | 35, 5, 1, 35 |
7 | 7, 1, 1, 7 |
1, 1, 1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 7 x 1 x 1 x 1 x 1 = 630
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/630
Therefore, the GCF of Fractions 58/70,22/45,87/18,56/70 is 1/630
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 70,45,18,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,45,18,70) = 1
common factors(in case of two or more numbers have common factors) = 6300
GCF(70,45,18,70) x common factors =1 x 6300 = 6300
LCM(70,45,18,70) = ( 70 × 45 × 18 × 70 ) / 6300
LCM(70,45,18,70) = 3969000 / 6300
LCM(70,45,18,70) = 630
