Given numbers are 642,535,124,187

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

The LCM of 642,535,124,187 is 37216740.

Find LCM of 642,535,124,187 with Prime Factorization

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

2 x 107 x 3 x 5 x 62 x 187 = 37216740

Therefore, the lowest common multiple of 642,535,124,187 is 37216740.

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 535 x 124 x 187 = 7964382360

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

535 : 1, 5, 107, 535

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

187 : 1, 11, 17, 187

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,535,124,187, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

535:5x 107

124:2x 2x 31

187:11x 17

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

2x 107 = 214

Therefore, the value for common factors is 214.

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 = 7964382360/(1x214)

LCM = 7964382360/214

LCM = 37216740

Thus, we can understand that the LCM of 642,535,124,187 is 37216740.
