Given numbers are 138,399,506,511
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 138,399,506,511 is 14738262.
Find LCM of 138,399,506,511 with Prime Factorization
| 2 | 138, 399, 506, 511 |
| 3 | 69, 399, 253, 511 |
| 7 | 23, 133, 253, 511 |
| 23 | 23, 19, 253, 73 |
| 1, 19, 11, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 1 x 19 x 11 x 73 = 14738262
Therefore, the lowest common multiple of 138,399,506,511 is 14738262.
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.
138 x 399 x 506 x 511 = 14237161092
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.
138 : 1, 2, 3, 6, 23, 46, 69, 138
399 : 1, 3, 7, 19, 21, 57, 133, 399
506 : 1, 2, 11, 22, 23, 46, 253, 506
511 : 1, 7, 73, 511
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,399,506,511, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
399:3x 7x 19
506:2x 11x 23
511:7x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 23 = 966
Therefore, the value for common factors is 966.
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 = 14237161092/(1x966)
LCM = 14237161092/966
LCM = 14738262
Thus, we can understand that the LCM of 138,399,506,511 is 14738262.
