Find LCM of 391,738,495,943,779 with Prime Factorization
| 3 | 391, 738, 495, 943, 779 |
| 3 | 391, 246, 165, 943, 779 |
| 23 | 391, 82, 55, 943, 779 |
| 41 | 17, 82, 55, 41, 779 |
| 17, 2, 55, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 23 x 41 x 17 x 2 x 55 x 1 x 19 = 301543110
Therefore, the lowest common multiple of 391,738,495,943,779 is 301543110.
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.
391 x 738 x 495 x 943 x 779 = 104927051357370
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.
391 : 1, 17, 23, 391
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
943 : 1, 23, 41, 943
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,738,495,943,779, is 1.
Now, the common factors can be found like this.
391:17x 23
738:2x 3x 3x 41
495:3x 3x 5x 11
943:23x 41
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 23x 41x 41 = 347967
Therefore, the value for common factors is 347967.
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 = 104927051357370/(1x347967)
LCM = 104927051357370/347967
LCM = 301543110
Thus, we can understand that the LCM of 391,738,495,943,779 is 301543110.
