Find LCM of 795,217,780,432,321 with Prime Factorization
| 2 | 795, 217, 780, 432, 321 |
| 2 | 795, 217, 390, 216, 321 |
| 3 | 795, 217, 195, 108, 321 |
| 5 | 265, 217, 65, 36, 107 |
| 53, 217, 13, 36, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 53 x 217 x 13 x 36 x 107 = 34555444560
Therefore, the lowest common multiple of 795,217,780,432,321 is 34555444560.
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.
795 x 217 x 780 x 432 x 321 = 18659940062400
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.
795 : 1, 3, 5, 15, 53, 159, 265, 795
217 : 1, 7, 31, 217
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 795,217,780,432,321, is 1.
Now, the common factors can be found like this.
795:3x 5x 53
217:7x 31
780:2x 2x 3x 5x 13
432:2x 2x 2x 2x 3x 3x 3
321:3x 107
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 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 18659940062400/(1x540)
LCM = 18659940062400/540
LCM = 34555444560
Thus, we can understand that the LCM of 795,217,780,432,321 is 34555444560.
