Given numbers are 632,391,437,788,345
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 632,391,437,788,345 is 13874103240.
Find LCM of 632,391,437,788,345 with Prime Factorization
| 2 | 632, 391, 437, 788, 345 |
| 2 | 316, 391, 437, 394, 345 |
| 23 | 158, 391, 437, 197, 345 |
| 158, 17, 19, 197, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 158 x 17 x 19 x 197 x 15 = 13874103240
Therefore, the lowest common multiple of 632,391,437,788,345 is 13874103240.
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.
632 x 391 x 437 x 788 x 345 = 29357602455840
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.
632 : 1, 2, 4, 8, 79, 158, 316, 632
391 : 1, 17, 23, 391
437 : 1, 19, 23, 437
788 : 1, 2, 4, 197, 394, 788
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 632,391,437,788,345, is 1.
Now, the common factors can be found like this.
632:2x 2x 2x 79
391:17x 23
437:19x 23
788:2x 2x 197
345:3x 5x 23
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 23x 23 = 2116
Therefore, the value for common factors is 2116.
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 = 29357602455840/(1x2116)
LCM = 29357602455840/2116
LCM = 13874103240
Thus, we can understand that the LCM of 632,391,437,788,345 is 13874103240.
