Find LCM of 637,721,840,882,617 with Prime Factorization
| 2 | 637, 721, 840, 882, 617 |
| 3 | 637, 721, 420, 441, 617 |
| 7 | 637, 721, 140, 147, 617 |
| 7 | 91, 103, 20, 21, 617 |
| 13, 103, 20, 3, 617 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 7 x 13 x 103 x 20 x 3 x 617 = 14573515320
Therefore, the lowest common multiple of 637,721,840,882,617 is 14573515320.
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.
637 x 721 x 840 x 882 x 617 = 209946061699920
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.
637 : 1, 7, 13, 49, 91, 637
721 : 1, 7, 103, 721
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
617 : 1, 617
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,721,840,882,617, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
721:7x 103
840:2x 2x 2x 3x 5x 7
882:2x 3x 3x 7x 7
617:617
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 7x 7x 7x 7 = 14406
Therefore, the value for common factors is 14406.
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 = 209946061699920/(1x14406)
LCM = 209946061699920/14406
LCM = 14573515320
Thus, we can understand that the LCM of 637,721,840,882,617 is 14573515320.
