Given numbers are 6,978,403,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 6,978,403,403 is 394134.
Find LCM of 6,978,403,403 with Prime Factorization
| 2 | 6, 978, 403, 403 |
| 3 | 3, 489, 403, 403 |
| 13 | 1, 163, 403, 403 |
| 31 | 1, 163, 31, 31 |
| 1, 163, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 31 x 1 x 163 x 1 x 1 = 394134
Therefore, the lowest common multiple of 6,978,403,403 is 394134.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
6 x 978 x 403 x 403 = 953016012
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
6 : 1, 2, 3, 6
978 : 1, 2, 3, 6, 163, 326, 489, 978
403 : 1, 13, 31, 403
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6,978,403,403, is 1.
Now, the common factors can be found like this.
6:2x 3
978:2x 3x 163
403:13x 31
403:13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13x 31 = 2418
Therefore, the value for common factors is 2418.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 953016012/(1x2418)
LCM = 953016012/2418
LCM = 394134
Thus, we can understand that the LCM of 6,978,403,403 is 394134.
