Given numbers are 432,642,220,199,671
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 432,642,220,199,671 is 30861222480.
Find LCM of 432,642,220,199,671 with Prime Factorization
| 2 | 432, 642, 220, 199, 671 |
| 2 | 216, 321, 110, 199, 671 |
| 3 | 108, 321, 55, 199, 671 |
| 11 | 36, 107, 55, 199, 671 |
| 36, 107, 5, 199, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 36 x 107 x 5 x 199 x 61 = 30861222480
Therefore, the lowest common multiple of 432,642,220,199,671 is 30861222480.
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.
432 x 642 x 220 x 199 x 671 = 8147362734720
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.
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
642 : 1, 2, 3, 6, 107, 214, 321, 642
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
199 : 1, 199
671 : 1, 11, 61, 671
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,642,220,199,671, is 1.
Now, the common factors can be found like this.
432:2x 2x 2x 2x 3x 3x 3
642:2x 3x 107
220:2x 2x 5x 11
199:199
671:11x 61
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 2x 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 8147362734720/(1x264)
LCM = 8147362734720/264
LCM = 30861222480
Thus, we can understand that the LCM of 432,642,220,199,671 is 30861222480.
