Given numbers are 403,681,462,879,432
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,681,462,879,432 is 891606027312.
Find LCM of 403,681,462,879,432 with Prime Factorization
| 2 | 403, 681, 462, 879, 432 |
| 3 | 403, 681, 231, 879, 216 |
| 403, 227, 77, 293, 72 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 403 x 227 x 77 x 293 x 72 = 891606027312
Therefore, the lowest common multiple of 403,681,462,879,432 is 891606027312.
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.
403 x 681 x 462 x 879 x 432 = 48146725474848
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.
403 : 1, 13, 31, 403
681 : 1, 3, 227, 681
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
879 : 1, 3, 293, 879
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,681,462,879,432, is 1.
Now, the common factors can be found like this.
403:13x 31
681:3x 227
462:2x 3x 7x 11
879:3x 293
432:2x 2x 2x 2x 3x 3x 3
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 3 = 54
Therefore, the value for common factors is 54.
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 = 48146725474848/(1x54)
LCM = 48146725474848/54
LCM = 891606027312
Thus, we can understand that the LCM of 403,681,462,879,432 is 891606027312.
