Given numbers are 406,149,780,312
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 406,149,780,312 is 47185320.
Find LCM of 406,149,780,312 with Prime Factorization
| 2 | 406, 149, 780, 312 |
| 2 | 203, 149, 390, 156 |
| 3 | 203, 149, 195, 78 |
| 13 | 203, 149, 65, 26 |
| 203, 149, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 203 x 149 x 5 x 2 = 47185320
Therefore, the lowest common multiple of 406,149,780,312 is 47185320.
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.
406 x 149 x 780 x 312 = 14721819840
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.
406 : 1, 2, 7, 14, 29, 58, 203, 406
149 : 1, 149
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,149,780,312, is 1.
Now, the common factors can be found like this.
406:2x 7x 29
149:149
780:2x 2x 3x 5x 13
312:2x 2x 2x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 13 = 312
Therefore, the value for common factors is 312.
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 = 14721819840/(1x312)
LCM = 14721819840/312
LCM = 47185320
Thus, we can understand that the LCM of 406,149,780,312 is 47185320.
