Given numbers are 782,187,429,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,187,429,765 is 5032170.
Find LCM of 782,187,429,765 with Prime Factorization
| 3 | 782, 187, 429, 765 |
| 11 | 782, 187, 143, 255 |
| 17 | 782, 17, 13, 255 |
| 46, 1, 13, 15 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 17 x 46 x 1 x 13 x 15 = 5032170
Therefore, the lowest common multiple of 782,187,429,765 is 5032170.
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.
782 x 187 x 429 x 765 = 47991805290
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
187 : 1, 11, 17, 187
429 : 1, 3, 11, 13, 33, 39, 143, 429
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,187,429,765, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
187:11x 17
429:3x 11x 13
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 17x 17 = 9537
Therefore, the value for common factors is 9537.
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 = 47991805290/(1x9537)
LCM = 47991805290/9537
LCM = 5032170
Thus, we can understand that the LCM of 782,187,429,765 is 5032170.
