Given numbers are 417,399,681,374,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 417,399,681,374,391 is 108296143494.
Find LCM of 417,399,681,374,391 with Prime Factorization
| 3 | 417, 399, 681, 374, 391 |
| 17 | 139, 133, 227, 374, 391 |
| 139, 133, 227, 22, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 139 x 133 x 227 x 22 x 23 = 108296143494
Therefore, the lowest common multiple of 417,399,681,374,391 is 108296143494.
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.
417 x 399 x 681 x 374 x 391 = 16569309954582
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.
417 : 1, 3, 139, 417
399 : 1, 3, 7, 19, 21, 57, 133, 399
681 : 1, 3, 227, 681
374 : 1, 2, 11, 17, 22, 34, 187, 374
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,399,681,374,391, is 1.
Now, the common factors can be found like this.
417:3x 139
399:3x 7x 19
681:3x 227
374:2x 11x 17
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 17 = 153
Therefore, the value for common factors is 153.
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 = 16569309954582/(1x153)
LCM = 16569309954582/153
LCM = 108296143494
Thus, we can understand that the LCM of 417,399,681,374,391 is 108296143494.
