Given numbers are 407,357,642,356,555
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 407,357,642,356,555 is 27673647540.
Find LCM of 407,357,642,356,555 with Prime Factorization
| 2 | 407, 357, 642, 356, 555 |
| 3 | 407, 357, 321, 178, 555 |
| 37 | 407, 119, 107, 178, 185 |
| 11, 119, 107, 178, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 37 x 11 x 119 x 107 x 178 x 5 = 27673647540
Therefore, the lowest common multiple of 407,357,642,356,555 is 27673647540.
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.
407 x 357 x 642 x 356 x 555 = 18430649261640
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.
407 : 1, 11, 37, 407
357 : 1, 3, 7, 17, 21, 51, 119, 357
642 : 1, 2, 3, 6, 107, 214, 321, 642
356 : 1, 2, 4, 89, 178, 356
555 : 1, 3, 5, 15, 37, 111, 185, 555
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,357,642,356,555, is 1.
Now, the common factors can be found like this.
407:11x 37
357:3x 7x 17
642:2x 3x 107
356:2x 2x 89
555:3x 5x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 37 = 666
Therefore, the value for common factors is 666.
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 = 18430649261640/(1x666)
LCM = 18430649261640/666
LCM = 27673647540
Thus, we can understand that the LCM of 407,357,642,356,555 is 27673647540.
