Given numbers are 642,915,362,229,117
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,915,362,229,117 is 316529018910.
Find LCM of 642,915,362,229,117 with Prime Factorization
| 2 | 642, 915, 362, 229, 117 |
| 3 | 321, 915, 181, 229, 117 |
| 107, 305, 181, 229, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 305 x 181 x 229 x 39 = 316529018910
Therefore, the lowest common multiple of 642,915,362,229,117 is 316529018910.
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.
642 x 915 x 362 x 229 x 117 = 5697522340380
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
915 : 1, 3, 5, 15, 61, 183, 305, 915
362 : 1, 2, 181, 362
229 : 1, 229
117 : 1, 3, 9, 13, 39, 117
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,915,362,229,117, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
915:3x 5x 61
362:2x 181
229:229
117:3x 3x 13
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 3 = 18
Therefore, the value for common factors is 18.
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 = 5697522340380/(1x18)
LCM = 5697522340380/18
LCM = 316529018910
Thus, we can understand that the LCM of 642,915,362,229,117 is 316529018910.
