Find LCM of 780,943,429,535 with Prime Factorization
| 3 | 780, 943, 429, 535 |
| 5 | 260, 943, 143, 535 |
| 13 | 52, 943, 143, 107 |
| 4, 943, 11, 107 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 4 x 943 x 11 x 107 = 865730580
Therefore, the lowest common multiple of 780,943,429,535 is 865730580.
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.
780 x 943 x 429 x 535 = 168817463100
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.
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
943 : 1, 23, 41, 943
429 : 1, 3, 11, 13, 33, 39, 143, 429
535 : 1, 5, 107, 535
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,943,429,535, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
943:23x 41
429:3x 11x 13
535:5x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13 = 195
Therefore, the value for common factors is 195.
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 = 168817463100/(1x195)
LCM = 168817463100/195
LCM = 865730580
Thus, we can understand that the LCM of 780,943,429,535 is 865730580.
