Given numbers are 391,749,943,837,102
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,749,943,837,102 is 20100084606.
Find LCM of 391,749,943,837,102 with Prime Factorization
| 3 | 391, 749, 943, 837, 102 |
| 17 | 391, 749, 943, 279, 34 |
| 23 | 23, 749, 943, 279, 2 |
| 1, 749, 41, 279, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 23 x 1 x 749 x 41 x 279 x 2 = 20100084606
Therefore, the lowest common multiple of 391,749,943,837,102 is 20100084606.
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.
391 x 749 x 943 x 837 x 102 = 23577399242838
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.
391 : 1, 17, 23, 391
749 : 1, 7, 107, 749
943 : 1, 23, 41, 943
837 : 1, 3, 9, 27, 31, 93, 279, 837
102 : 1, 2, 3, 6, 17, 34, 51, 102
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,749,943,837,102, is 1.
Now, the common factors can be found like this.
391:17x 23
749:7x 107
943:23x 41
837:3x 3x 3x 31
102:2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17x 23 = 1173
Therefore, the value for common factors is 1173.
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 = 23577399242838/(1x1173)
LCM = 23577399242838/1173
LCM = 20100084606
Thus, we can understand that the LCM of 391,749,943,837,102 is 20100084606.
