Given numbers are 422,633,421,665

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

The LCM of 422,633,421,665 is 354435690.

Find LCM of 422,633,421,665 with Prime Factorization

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

211 x 2 x 3 x 421 x 665 = 354435690

Therefore, the lowest common multiple of 422,633,421,665 is 354435690.

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.

422 x 633 x 421 x 665 = 74785930590

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.

422 : 1, 2, 211, 422

633 : 1, 3, 211, 633

421 : 1, 421

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,633,421,665, is 1.

Now, the common factors can be found like this.

422:2x 211

633:3x 211

421:421

665:5x 7x 19

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

211 = 211

Therefore, the value for common factors is 211.

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 = 74785930590/(1x211)

LCM = 74785930590/211

LCM = 354435690

Thus, we can understand that the LCM of 422,633,421,665 is 354435690.
