Given numbers are 268,838,506,772
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 268,838,506,772 is 5483106068.
Find LCM of 268,838,506,772 with Prime Factorization
| 2 | 268, 838, 506, 772 |
| 2 | 134, 419, 253, 386 |
| 67, 419, 253, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 67 x 419 x 253 x 193 = 5483106068
Therefore, the lowest common multiple of 268,838,506,772 is 5483106068.
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.
268 x 838 x 506 x 772 = 87729697088
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.
268 : 1, 2, 4, 67, 134, 268
838 : 1, 2, 419, 838
506 : 1, 2, 11, 22, 23, 46, 253, 506
772 : 1, 2, 4, 193, 386, 772
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 268,838,506,772, is 2.
Now, the common factors can be found like this.
268:2x 2x 67
838:2x 419
506:2x 11x 23
772:2x 2x 193
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 2 = 8
Therefore, the value for common factors is 8.
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 = 87729697088/(2x8)
LCM = 87729697088/16
LCM = 5483106068
Thus, we can understand that the LCM of 268,838,506,772 is 5483106068.
