The LCM of 403,624,514,784 is 243598992.
Find LCM of 403,624,514,784 with Prime Factorization
| 2 | 403, 624, 514, 784 |
| 2 | 403, 312, 257, 392 |
| 2 | 403, 156, 257, 196 |
| 2 | 403, 78, 257, 98 |
| 13 | 403, 39, 257, 49 |
| 31, 3, 257, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 13 x 31 x 3 x 257 x 49 = 243598992
Therefore, the lowest common multiple of 403,624,514,784 is 243598992.
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 624 x 514 x 784 = 101337180672
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
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
514 : 1, 2, 257, 514
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,624,514,784, is 1.
Now, the common factors can be found like this.
403:13x 31
624:2x 2x 2x 2x 3x 13
514:2x 257
784:2x 2x 2x 2x 7x 7
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 13 = 416
Therefore, the value for common factors is 416.
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 = 101337180672/(1x416)
LCM = 101337180672/416
LCM = 243598992
Thus, we can understand that the LCM of 403,624,514,784 is 243598992.
