Given numbers are 615,697,887,731,746
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,697,887,731,746 is 297478059630.
Find LCM of 615,697,887,731,746 with Prime Factorization
| 17 | 615, 697, 887, 731, 746 |
| 41 | 615, 41, 887, 43, 746 |
| 15, 1, 887, 43, 746 |
Multiply the prime numbers at the bottom and the left side.
17 x 41 x 15 x 1 x 887 x 43 x 746 = 297478059630
Therefore, the lowest common multiple of 615,697,887,731,746 is 297478059630.
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 697 x 887 x 731 x 746 = 207342207562110
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
697 : 1, 17, 41, 697
887 : 1, 887
731 : 1, 17, 43, 731
746 : 1, 2, 373, 746
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,697,887,731,746, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
697:17x 41
887:887
731:17x 43
746:2x 373
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 41 = 697
Therefore, the value for common factors is 697.
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 = 207342207562110/(1x697)
LCM = 207342207562110/697
LCM = 297478059630
Thus, we can understand that the LCM of 615,697,887,731,746 is 297478059630.
