Find LCM of 346,645,514,715,780 with Prime Factorization
| 2 | 346, 645, 514, 715, 780 |
| 3 | 173, 645, 257, 715, 390 |
| 5 | 173, 215, 257, 715, 130 |
| 13 | 173, 43, 257, 143, 26 |
| 173, 43, 257, 11, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 173 x 43 x 257 x 11 x 2 = 16403441340
Therefore, the lowest common multiple of 346,645,514,715,780 is 16403441340.
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.
346 x 645 x 514 x 715 x 780 = 63973421226000
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.
346 : 1, 2, 173, 346
645 : 1, 3, 5, 15, 43, 129, 215, 645
514 : 1, 2, 257, 514
715 : 1, 5, 11, 13, 55, 65, 143, 715
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 346,645,514,715,780, is 1.
Now, the common factors can be found like this.
346:2x 173
645:3x 5x 43
514:2x 257
715:5x 11x 13
780:2x 2x 3x 5x 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 5x 5x 13 = 3900
Therefore, the value for common factors is 3900.
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 = 63973421226000/(1x3900)
LCM = 63973421226000/3900
LCM = 16403441340
Thus, we can understand that the LCM of 346,645,514,715,780 is 16403441340.
