Given numbers are 838,506,138,552
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,506,138,552 is 2544168.
Find LCM of 838,506,138,552 with Prime Factorization
| 2 | 838, 506, 138, 552 |
| 3 | 419, 253, 69, 276 |
| 23 | 419, 253, 23, 92 |
| 419, 11, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 419 x 11 x 1 x 4 = 2544168
Therefore, the lowest common multiple of 838,506,138,552 is 2544168.
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.
838 x 506 x 138 x 552 = 32300756928
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.
838 : 1, 2, 419, 838
506 : 1, 2, 11, 22, 23, 46, 253, 506
138 : 1, 2, 3, 6, 23, 46, 69, 138
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,506,138,552, is 2.
Now, the common factors can be found like this.
838:2x 419
506:2x 11x 23
138:2x 3x 23
552:2x 2x 2x 3x 23
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 3x 23x 23 = 6348
Therefore, the value for common factors is 6348.
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 = 32300756928/(2x6348)
LCM = 32300756928/12696
LCM = 2544168
Thus, we can understand that the LCM of 838,506,138,552 is 2544168.
