Given numbers are 783,639,630,851,382
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 783,639,630,851,382 is 632529926910.
Find LCM of 783,639,630,851,382 with Prime Factorization
| 2 | 783, 639, 630, 851, 382 |
| 3 | 783, 639, 315, 851, 191 |
| 3 | 261, 213, 105, 851, 191 |
| 87, 71, 35, 851, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 87 x 71 x 35 x 851 x 191 = 632529926910
Therefore, the lowest common multiple of 783,639,630,851,382 is 632529926910.
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.
783 x 639 x 630 x 851 x 382 = 102469848159420
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
639 : 1, 3, 9, 71, 213, 639
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
851 : 1, 23, 37, 851
382 : 1, 2, 191, 382
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,639,630,851,382, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
639:3x 3x 71
630:2x 3x 3x 5x 7
851:23x 37
382:2x 191
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 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 102469848159420/(1x162)
LCM = 102469848159420/162
LCM = 632529926910
Thus, we can understand that the LCM of 783,639,630,851,382 is 632529926910.
