Given numbers are 368,403,620,349
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 368,403,620,349 is 258790480.
Find LCM of 368,403,620,349 with Prime Factorization
| 2 | 368, 403, 620, 349 |
| 2 | 184, 403, 310, 349 |
| 31 | 92, 403, 155, 349 |
| 92, 13, 5, 349 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 92 x 13 x 5 x 349 = 258790480
Therefore, the lowest common multiple of 368,403,620,349 is 258790480.
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.
368 x 403 x 620 x 349 = 32090019520
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.
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
403 : 1, 13, 31, 403
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
349 : 1, 349
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 368,403,620,349, is 1.
Now, the common factors can be found like this.
368:2x 2x 2x 2x 23
403:13x 31
620:2x 2x 5x 31
349:349
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 31 = 124
Therefore, the value for common factors is 124.
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 = 32090019520/(1x124)
LCM = 32090019520/124
LCM = 258790480
Thus, we can understand that the LCM of 368,403,620,349 is 258790480.
