Given numbers are 638,923,113,284

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

The LCM of 638,923,113,284 is 133085524.

Find LCM of 638,923,113,284 with Prime Factorization

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

2 x 71 x 319 x 13 x 113 x 2 = 133085524

Therefore, the lowest common multiple of 638,923,113,284 is 133085524.

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 923 x 113 x 284 = 18898144408

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

923 : 1, 13, 71, 923

113 : 1, 113

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,923,113,284, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

923:13x 71

113:113

284:2x 2x 71

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

2x 71 = 142

Therefore, the value for common factors is 142.

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 = 18898144408/(1x142)

LCM = 18898144408/142

LCM = 133085524

Thus, we can understand that the LCM of 638,923,113,284 is 133085524.
