Given numbers are 642,521,958,222

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

The LCM of 642,521,958,222 is 5928024486.

Find LCM of 642,521,958,222 with Prime Factorization

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

2 x 3 x 107 x 521 x 479 x 37 = 5928024486

Therefore, the lowest common multiple of 642,521,958,222 is 5928024486.

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 521 x 958 x 222 = 71136293832

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

521 : 1, 521

958 : 1, 2, 479, 958

222 : 1, 2, 3, 6, 37, 74, 111, 222

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,521,958,222, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

521:521

958:2x 479

222:2x 3x 37

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 3 = 12

Therefore, the value for common factors is 12.

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 = 71136293832/(1x12)

LCM = 71136293832/12

LCM = 5928024486

Thus, we can understand that the LCM of 642,521,958,222 is 5928024486.
