Given numbers are 736,391,238,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 736,391,238,391 is 87584.
Find LCM of 736,391,238,391 with Prime Factorization
| 2 | 736, 391, 238, 391 |
| 17 | 368, 391, 119, 391 |
| 23 | 368, 23, 7, 23 |
| 16, 1, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 16 x 1 x 7 x 1 = 87584
Therefore, the lowest common multiple of 736,391,238,391 is 87584.
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.
736 x 391 x 238 x 391 = 26779859008
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.
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
391 : 1, 17, 23, 391
238 : 1, 2, 7, 14, 17, 34, 119, 238
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 736,391,238,391, is 1.
Now, the common factors can be found like this.
736:2x 2x 2x 2x 2x 23
391:17x 23
238:2x 7x 17
391:17x 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 17x 17x 23x 23 = 305762
Therefore, the value for common factors is 305762.
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 = 26779859008/(1x305762)
LCM = 26779859008/305762
LCM = 87584
Thus, we can understand that the LCM of 736,391,238,391 is 87584.
