Given numbers are 643,451,358,798

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

The LCM of 643,451,358,798 is 41423180106.

Find LCM of 643,451,358,798 with Prime Factorization

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

2 x 643 x 451 x 179 x 399 = 41423180106

Therefore, the lowest common multiple of 643,451,358,798 is 41423180106.

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.

643 x 451 x 358 x 798 = 82846360212

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.

643 : 1, 643

451 : 1, 11, 41, 451

358 : 1, 2, 179, 358

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,451,358,798, is 1.

Now, the common factors can be found like this.

643:643

451:11x 41

358:2x 179

798:2x 3x 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.

2 = 2

Therefore, the value for common factors is 2.

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 = 82846360212/(1x2)

LCM = 82846360212/2

LCM = 41423180106

Thus, we can understand that the LCM of 643,451,358,798 is 41423180106.
