Given numbers are 638,475,698,231

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

The LCM of 638,475,698,231 is 2221053450.

Find LCM of 638,475,698,231 with Prime Factorization

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

2 x 11 x 29 x 475 x 349 x 21 = 2221053450

Therefore, the lowest common multiple of 638,475,698,231 is 2221053450.

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.

638 x 475 x 698 x 231 = 48863175900

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

475 : 1, 5, 19, 25, 95, 475

698 : 1, 2, 349, 698

231 : 1, 3, 7, 11, 21, 33, 77, 231

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,475,698,231, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

475:5x 5x 19

698:2x 349

231:3x 7x 11

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 48863175900/(1x22)

LCM = 48863175900/22

LCM = 2221053450

Thus, we can understand that the LCM of 638,475,698,231 is 2221053450.
