Given numbers are 531,761,668,642

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

The LCM of 531,761,668,642 is 28882808316.

Find LCM of 531,761,668,642 with Prime Factorization

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

2 x 3 x 177 x 761 x 334 x 107 = 28882808316

Therefore, the lowest common multiple of 531,761,668,642 is 28882808316.

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.

531 x 761 x 668 x 642 = 173296849896

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.

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

761 : 1, 761

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

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,761,668,642, is 1.

Now, the common factors can be found like this.

531:3x 3x 59

761:761

668:2x 2x 167

642:2x 3x 107

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 173296849896/(1x6)

LCM = 173296849896/6

LCM = 28882808316

Thus, we can understand that the LCM of 531,761,668,642 is 28882808316.
