Given numbers are 642,115,452,981,841

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 642,115,452,981,841 is 4588651299060.

Find LCM of 642,115,452,981,841 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 107 x 115 x 226 x 327 x 841 = 4588651299060

Therefore, the lowest common multiple of 642,115,452,981,841 is 4588651299060.

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.

642 x 115 x 452 x 981 x 841 = 27531907794360

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

115 : 1, 5, 23, 115

452 : 1, 2, 4, 113, 226, 452

981 : 1, 3, 9, 109, 327, 981

841 : 1, 29, 841

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,115,452,981,841, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

115:5x 23

452:2x 2x 113

981:3x 3x 109

841:29x 29

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 27531907794360/(1x6)

LCM = 27531907794360/6

LCM = 4588651299060

Thus, we can understand that the LCM of 642,115,452,981,841 is 4588651299060.
