Given numbers are 615,731,178,780,267
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,731,178,780,267 is 2080586820.
Find LCM of 615,731,178,780,267 with Prime Factorization
| 2 | 615, 731, 178, 780, 267 |
| 3 | 615, 731, 89, 390, 267 |
| 5 | 205, 731, 89, 130, 89 |
| 89 | 41, 731, 89, 26, 89 |
| 41, 731, 1, 26, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 89 x 41 x 731 x 1 x 26 x 1 = 2080586820
Therefore, the lowest common multiple of 615,731,178,780,267 is 2080586820.
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.
615 x 731 x 178 x 780 x 267 = 16665500428200
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
731 : 1, 17, 43, 731
178 : 1, 2, 89, 178
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
267 : 1, 3, 89, 267
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,731,178,780,267, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
731:17x 43
178:2x 89
780:2x 2x 3x 5x 13
267:3x 89
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 3x 5x 89 = 8010
Therefore, the value for common factors is 8010.
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 = 16665500428200/(1x8010)
LCM = 16665500428200/8010
LCM = 2080586820
Thus, we can understand that the LCM of 615,731,178,780,267 is 2080586820.
