Given numbers are 230,642,921,942

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

The LCM of 230,642,921,942 is 3558532170.

Find LCM of 230,642,921,942 with Prime Factorization

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

2 x 3 x 115 x 107 x 307 x 157 = 3558532170

Therefore, the lowest common multiple of 230,642,921,942 is 3558532170.

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.

230 x 642 x 921 x 942 = 128107158120

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.

230 : 1, 2, 5, 10, 23, 46, 115, 230

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

921 : 1, 3, 307, 921

942 : 1, 2, 3, 6, 157, 314, 471, 942

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 230,642,921,942, is 1.

Now, the common factors can be found like this.

230:2x 5x 23

642:2x 3x 107

921:3x 307

942:2x 3x 157

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

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 128107158120/(1x36)

LCM = 128107158120/36

LCM = 3558532170

Thus, we can understand that the LCM of 230,642,921,942 is 3558532170.
