Given numbers are 421,669,358,892

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

The LCM of 421,669,358,892 is 201660684.

Find LCM of 421,669,358,892 with Prime Factorization

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

2 x 223 x 421 x 3 x 179 x 2 = 201660684

Therefore, the lowest common multiple of 421,669,358,892 is 201660684.

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.

421 x 669 x 358 x 892 = 89940665064

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.

421 : 1, 421

669 : 1, 3, 223, 669

358 : 1, 2, 179, 358

892 : 1, 2, 4, 223, 446, 892

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,669,358,892, is 1.

Now, the common factors can be found like this.

421:421

669:3x 223

358:2x 179

892:2x 2x 223

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

2x 223 = 446

Therefore, the value for common factors is 446.

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 = 89940665064/(1x446)

LCM = 89940665064/446

LCM = 201660684

Thus, we can understand that the LCM of 421,669,358,892 is 201660684.
