Given numbers are 508,678,393,762
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 508,678,393,762 is 22559772.
Find LCM of 508,678,393,762 with Prime Factorization
| 2 | 508, 678, 393, 762 |
| 3 | 254, 339, 393, 381 |
| 127 | 254, 113, 131, 127 |
| 2, 113, 131, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 127 x 2 x 113 x 131 x 1 = 22559772
Therefore, the lowest common multiple of 508,678,393,762 is 22559772.
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.
508 x 678 x 393 x 762 = 103143277584
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.
508 : 1, 2, 4, 127, 254, 508
678 : 1, 2, 3, 6, 113, 226, 339, 678
393 : 1, 3, 131, 393
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 508,678,393,762, is 1.
Now, the common factors can be found like this.
508:2x 2x 127
678:2x 3x 113
393:3x 131
762:2x 3x 127
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 3x 127 = 4572
Therefore, the value for common factors is 4572.
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 = 103143277584/(1x4572)
LCM = 103143277584/4572
LCM = 22559772
Thus, we can understand that the LCM of 508,678,393,762 is 22559772.
