Given numbers are 731,442,671,540,386
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,442,671,540,386 is 664560184860.
Find LCM of 731,442,671,540,386 with Prime Factorization
| 2 | 731, 442, 671, 540, 386 |
| 17 | 731, 221, 671, 270, 193 |
| 43, 13, 671, 270, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 43 x 13 x 671 x 270 x 193 = 664560184860
Therefore, the lowest common multiple of 731,442,671,540,386 is 664560184860.
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.
731 x 442 x 671 x 540 x 386 = 45190092570480
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.
731 : 1, 17, 43, 731
442 : 1, 2, 13, 17, 26, 34, 221, 442
671 : 1, 11, 61, 671
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
386 : 1, 2, 193, 386
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,442,671,540,386, is 1.
Now, the common factors can be found like this.
731:17x 43
442:2x 13x 17
671:11x 61
540:2x 2x 3x 3x 3x 5
386:2x 193
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 17 = 68
Therefore, the value for common factors is 68.
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 = 45190092570480/(1x68)
LCM = 45190092570480/68
LCM = 664560184860
Thus, we can understand that the LCM of 731,442,671,540,386 is 664560184860.
