Given numbers are 391,137,236,644,852
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,137,236,644,852 is 18848941692.
Find LCM of 391,137,236,644,852 with Prime Factorization
| 2 | 391, 137, 236, 644, 852 |
| 2 | 391, 137, 118, 322, 426 |
| 23 | 391, 137, 59, 161, 213 |
| 17, 137, 59, 7, 213 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 17 x 137 x 59 x 7 x 213 = 18848941692
Therefore, the lowest common multiple of 391,137,236,644,852 is 18848941692.
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 137 x 236 x 644 x 852 = 6936410542656
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
137 : 1, 137
236 : 1, 2, 4, 59, 118, 236
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,137,236,644,852, is 1.
Now, the common factors can be found like this.
391:17x 23
137:137
236:2x 2x 59
644:2x 2x 7x 23
852:2x 2x 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 2x 23 = 368
Therefore, the value for common factors is 368.
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 = 6936410542656/(1x368)
LCM = 6936410542656/368
LCM = 18848941692
Thus, we can understand that the LCM of 391,137,236,644,852 is 18848941692.
