Given numbers are 431,131,431,638

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

The LCM of 431,131,431,638 is 36022118.

Find LCM of 431,131,431,638 with Prime Factorization

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

431 x 1 x 131 x 1 x 638 = 36022118

Therefore, the lowest common multiple of 431,131,431,638 is 36022118.

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.

431 x 131 x 431 x 638 = 15525532858

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.

431 : 1, 431

131 : 1, 131

431 : 1, 431

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,131,431,638, is 1.

Now, the common factors can be found like this.

431:431

131:131

431:431

638:2x 11x 29

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

431 = 431

Therefore, the value for common factors is 431.

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 = 15525532858/(1x431)

LCM = 15525532858/431

LCM = 36022118

Thus, we can understand that the LCM of 431,131,431,638 is 36022118.
