The LCM of 403,836,530,604,780 is 40444120860.
Find LCM of 403,836,530,604,780 with Prime Factorization
| 2 | 403, 836, 530, 604, 780 |
| 2 | 403, 418, 265, 302, 390 |
| 5 | 403, 209, 265, 151, 195 |
| 13 | 403, 209, 53, 151, 39 |
| 31, 209, 53, 151, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 31 x 209 x 53 x 151 x 3 = 40444120860
Therefore, the lowest common multiple of 403,836,530,604,780 is 40444120860.
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.
403 x 836 x 530 x 604 x 780 = 84123771388800
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.
403 : 1, 13, 31, 403
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
530 : 1, 2, 5, 10, 53, 106, 265, 530
604 : 1, 2, 4, 151, 302, 604
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 403,836,530,604,780, is 1.
Now, the common factors can be found like this.
403:13x 31
836:2x 2x 11x 19
530:2x 5x 53
604:2x 2x 151
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 2x 2x 2x 5x 13 = 2080
Therefore, the value for common factors is 2080.
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 = 84123771388800/(1x2080)
LCM = 84123771388800/2080
LCM = 40444120860
Thus, we can understand that the LCM of 403,836,530,604,780 is 40444120860.
