Find LCM of 630,488,397,284,639 with Prime Factorization
| 2 | 630, 488, 397, 284, 639 |
| 2 | 315, 244, 397, 142, 639 |
| 3 | 315, 122, 397, 71, 639 |
| 3 | 105, 122, 397, 71, 213 |
| 71 | 35, 122, 397, 71, 71 |
| 35, 122, 397, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 71 x 35 x 122 x 397 x 1 x 1 = 4332905640
Therefore, the lowest common multiple of 630,488,397,284,639 is 4332905640.
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.
630 x 488 x 397 x 284 x 639 = 22149813631680
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
488 : 1, 2, 4, 8, 61, 122, 244, 488
397 : 1, 397
284 : 1, 2, 4, 71, 142, 284
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,488,397,284,639, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
488:2x 2x 2x 61
397:397
284:2x 2x 71
639:3x 3x 71
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 3x 3x 71 = 5112
Therefore, the value for common factors is 5112.
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 = 22149813631680/(1x5112)
LCM = 22149813631680/5112
LCM = 4332905640
Thus, we can understand that the LCM of 630,488,397,284,639 is 4332905640.
