The LCM of 371,442,656,399,247 is 3065807472.
Find LCM of 371,442,656,399,247 with Prime Factorization
| 2 | 371, 442, 656, 399, 247 |
| 7 | 371, 221, 328, 399, 247 |
| 13 | 53, 221, 328, 57, 247 |
| 19 | 53, 17, 328, 57, 19 |
| 53, 17, 328, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 19 x 53 x 17 x 328 x 3 x 1 = 3065807472
Therefore, the lowest common multiple of 371,442,656,399,247 is 3065807472.
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.
371 x 442 x 656 x 399 x 247 = 10601562238176
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.
371 : 1, 7, 53, 371
442 : 1, 2, 13, 17, 26, 34, 221, 442
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
399 : 1, 3, 7, 19, 21, 57, 133, 399
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 371,442,656,399,247, is 1.
Now, the common factors can be found like this.
371:7x 53
442:2x 13x 17
656:2x 2x 2x 2x 41
399:3x 7x 19
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 13x 19 = 3458
Therefore, the value for common factors is 3458.
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 = 10601562238176/(1x3458)
LCM = 10601562238176/3458
LCM = 3065807472
Thus, we can understand that the LCM of 371,442,656,399,247 is 3065807472.
