Given numbers are 631,401,426,284

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

The LCM of 631,401,426,284 is 215582412.

Find LCM of 631,401,426,284 with Prime Factorization

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

2 x 71 x 631 x 401 x 3 x 2 = 215582412

Therefore, the lowest common multiple of 631,401,426,284 is 215582412.

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.

631 x 401 x 426 x 284 = 30612702504

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.

631 : 1, 631

401 : 1, 401

426 : 1, 2, 3, 6, 71, 142, 213, 426

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,401,426,284, is 1.

Now, the common factors can be found like this.

631:631

401:401

426:2x 3x 71

284:2x 2x 71

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

2x 71 = 142

Therefore, the value for common factors is 142.

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 = 30612702504/(1x142)

LCM = 30612702504/142

LCM = 215582412

Thus, we can understand that the LCM of 631,401,426,284 is 215582412.
