Given numbers are 638,207,323,154

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

The LCM of 638,207,323,154 is 298601226.

Find LCM of 638,207,323,154 with Prime Factorization

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

2 x 11 x 29 x 207 x 323 x 7 = 298601226

Therefore, the lowest common multiple of 638,207,323,154 is 298601226.

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 207 x 323 x 154 = 6569226972

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

207 : 1, 3, 9, 23, 69, 207

323 : 1, 17, 19, 323

154 : 1, 2, 7, 11, 14, 22, 77, 154

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,207,323,154, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

207:3x 3x 23

323:17x 19

154:2x 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 = 6569226972/(1x22)

LCM = 6569226972/22

LCM = 298601226

Thus, we can understand that the LCM of 638,207,323,154 is 298601226.
