Given numbers are 912,642,392,666,158
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 912,642,392,666,158 is 41929990704.
Find LCM of 912,642,392,666,158 with Prime Factorization
| 2 | 912, 642, 392, 666, 158 |
| 2 | 456, 321, 196, 333, 79 |
| 2 | 228, 321, 98, 333, 79 |
| 3 | 114, 321, 49, 333, 79 |
| 38, 107, 49, 111, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 38 x 107 x 49 x 111 x 79 = 41929990704
Therefore, the lowest common multiple of 912,642,392,666,158 is 41929990704.
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.
912 x 642 x 392 x 666 x 158 = 24151674645504
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
642 : 1, 2, 3, 6, 107, 214, 321, 642
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
158 : 1, 2, 79, 158
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,642,392,666,158, is 2.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
642:2x 3x 107
392:2x 2x 2x 7x 7
666:2x 3x 3x 37
158:2x 79
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 2x 2x 3x 3 = 288
Therefore, the value for common factors is 288.
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 = 24151674645504/(2x288)
LCM = 24151674645504/576
LCM = 41929990704
Thus, we can understand that the LCM of 912,642,392,666,158 is 41929990704.
