Given numbers are 642,157,855,741,910

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

The LCM of 642,157,855,741,910 is 2614092390.

Find LCM of 642,157,855,741,910 with Prime Factorization

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

2 x 3 x 5 x 13 x 19 x 107 x 157 x 3 x 1 x 7 = 2614092390

Therefore, the lowest common multiple of 642,157,855,741,910 is 2614092390.

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 157 x 855 x 741 x 910 = 58111273829700

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

157 : 1, 157

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

741 : 1, 3, 13, 19, 39, 57, 247, 741

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,157,855,741,910, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

157:157

855:3x 3x 5x 19

741:3x 13x 19

910:2x 5x 7x 13

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 5x 13x 19 = 22230

Therefore, the value for common factors is 22230.

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 = 58111273829700/(1x22230)

LCM = 58111273829700/22230

LCM = 2614092390

Thus, we can understand that the LCM of 642,157,855,741,910 is 2614092390.
