The LCM of 456,328,502,403,638 is 603278919672.
Find LCM of 456,328,502,403,638 with Prime Factorization
2 | 456, 328, 502, 403, 638 |
2 | 228, 164, 251, 403, 319 |
2 | 114, 82, 251, 403, 319 |
57, 41, 251, 403, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 57 x 41 x 251 x 403 x 319 = 603278919672
Therefore, the lowest common multiple of 456,328,502,403,638 is 603278919672.
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.
456 x 328 x 502 x 403 x 638 = 19304925429504
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.
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
328 : 1, 2, 4, 8, 41, 82, 164, 328
502 : 1, 2, 251, 502
403 : 1, 13, 31, 403
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,328,502,403,638, is 1.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
328:2x 2x 2x 41
502:2x 251
403:13x 31
638:2x 11x 29
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 2 = 32
Therefore, the value for common factors is 32.
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 = 19304925429504/(1x32)
LCM = 19304925429504/32
LCM = 603278919672
Thus, we can understand that the LCM of 456,328,502,403,638 is 603278919672.
