Given numbers are 631,322,455,621

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

The LCM of 631,322,455,621 is 356584410.

Find LCM of 631,322,455,621 with Prime Factorization

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

7 x 23 x 631 x 2 x 65 x 27 = 356584410

Therefore, the lowest common multiple of 631,322,455,621 is 356584410.

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 322 x 455 x 621 = 57410090010

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

322 : 1, 2, 7, 14, 23, 46, 161, 322

455 : 1, 5, 7, 13, 35, 65, 91, 455

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,322,455,621, is 1.

Now, the common factors can be found like this.

631:631

322:2x 7x 23

455:5x 7x 13

621:3x 3x 3x 23

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 57410090010/(1x161)

LCM = 57410090010/161

LCM = 356584410

Thus, we can understand that the LCM of 631,322,455,621 is 356584410.
