Given numbers are 638,668,531,751

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

The LCM of 638,668,531,751 is 84977040852.

Find LCM of 638,668,531,751 with Prime Factorization

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

2 x 319 x 334 x 531 x 751 = 84977040852

Therefore, the lowest common multiple of 638,668,531,751 is 84977040852.

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 668 x 531 x 751 = 169954081704

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

668 : 1, 2, 4, 167, 334, 668

531 : 1, 3, 9, 59, 177, 531

751 : 1, 751

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,668,531,751, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

668:2x 2x 167

531:3x 3x 59

751:751

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

2 = 2

Therefore, the value for common factors is 2.

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 = 169954081704/(1x2)

LCM = 169954081704/2

LCM = 84977040852

Thus, we can understand that the LCM of 638,668,531,751 is 84977040852.
