Given numbers are 123,392,707,421,382
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,392,707,421,382 is 391586774376.
Find LCM of 123,392,707,421,382 with Prime Factorization
| 2 | 123, 392, 707, 421, 382 |
| 7 | 123, 196, 707, 421, 191 |
| 123, 28, 101, 421, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 123 x 28 x 101 x 421 x 191 = 391586774376
Therefore, the lowest common multiple of 123,392,707,421,382 is 391586774376.
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.
123 x 392 x 707 x 421 x 382 = 5482214841264
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.
123 : 1, 3, 41, 123
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
707 : 1, 7, 101, 707
421 : 1, 421
382 : 1, 2, 191, 382
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,392,707,421,382, is 1.
Now, the common factors can be found like this.
123:3x 41
392:2x 2x 2x 7x 7
707:7x 101
421:421
382:2x 191
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 5482214841264/(1x14)
LCM = 5482214841264/14
LCM = 391586774376
Thus, we can understand that the LCM of 123,392,707,421,382 is 391586774376.
