1,2,7,14
Factors of 420
List of positive integer factors of 420 that divides 420 without a remainder.
1,2,3,4,5,6,7,10,12,14,15,20,21,28,30,35,42,60,70,84,105,140,210,420
Factors of 785
List of positive integer factors of 785 that divides 785 without a remainder.
1,5,157,785
Greatest Common Factor
We found the factors 14,420,785 . The biggest common factor number is the GCF number.
So the greatest common factor 14,420,785 is 1.
Lets's calculate LCM of 63,39,126
3 | 63, 39, 126 |
3 | 21, 13, 42 |
7 | 7, 13, 14 |
1, 13, 2 |
∴ So the LCM of the given numbers is 3 x 3 x 7 x 1 x 13 x 2 = 1638
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1638
Therefore, the GCF of Fractions 14/63,420/39,785/126 is 1/1638
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 63,39,126 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,39,126) = 3
common factors(in case of two or more numbers have common factors) = 63
GCF(63,39,126) x common factors =3 x 63 = 189
LCM(63,39,126) = ( 63 × 39 × 126 ) / 189
LCM(63,39,126) = 309582 / 189
LCM(63,39,126) = 1638
