Given numbers are 642,249,124,581

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

The LCM of 642,249,124,581 is 23126124.

Find LCM of 642,249,124,581 with Prime Factorization

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

2 x 3 x 83 x 107 x 1 x 62 x 7 = 23126124

Therefore, the lowest common multiple of 642,249,124,581 is 23126124.

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.

642 x 249 x 124 x 581 = 11516809752

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.

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

249 : 1, 3, 83, 249

124 : 1, 2, 4, 31, 62, 124

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,249,124,581, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

249:3x 83

124:2x 2x 31

581:7x 83

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

2x 3x 83 = 498

Therefore, the value for common factors is 498.

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 = 11516809752/(1x498)

LCM = 11516809752/498

LCM = 23126124

Thus, we can understand that the LCM of 642,249,124,581 is 23126124.
