Given numbers are 856,469,631,642

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

The LCM of 856,469,631,642 is 759971352.

Find LCM of 856,469,631,642 with Prime Factorization

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

2 x 107 x 4 x 469 x 631 x 3 = 759971352

Therefore, the lowest common multiple of 856,469,631,642 is 759971352.

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.

856 x 469 x 631 x 642 = 162633869328

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

469 : 1, 7, 67, 469

631 : 1, 631

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,469,631,642, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

469:7x 67

631:631

642:2x 3x 107

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

2x 107 = 214

Therefore, the value for common factors is 214.

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 = 162633869328/(1x214)

LCM = 162633869328/214

LCM = 759971352

Thus, we can understand that the LCM of 856,469,631,642 is 759971352.
