Given numbers are 662,154,993,858
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,154,993,858 is 1987986.
Find LCM of 662,154,993,858 with Prime Factorization
| 2 | 662, 154, 993, 858 |
| 3 | 331, 77, 993, 429 |
| 11 | 331, 77, 331, 143 |
| 331 | 331, 7, 331, 13 |
| 1, 7, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 331 x 1 x 7 x 1 x 13 = 1987986
Therefore, the lowest common multiple of 662,154,993,858 is 1987986.
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.
662 x 154 x 993 x 858 = 86859084312
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.
662 : 1, 2, 331, 662
154 : 1, 2, 7, 11, 14, 22, 77, 154
993 : 1, 3, 331, 993
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,154,993,858, is 1.
Now, the common factors can be found like this.
662:2x 331
154:2x 7x 11
993:3x 331
858:2x 3x 11x 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 2x 3x 11x 331 = 43692
Therefore, the value for common factors is 43692.
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 = 86859084312/(1x43692)
LCM = 86859084312/43692
LCM = 1987986
Thus, we can understand that the LCM of 662,154,993,858 is 1987986.
