Given numbers are 628,920,221,548

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

The LCM of 628,920,221,548 is 4373209880.

Find LCM of 628,920,221,548 with Prime Factorization

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

2 x 2 x 157 x 230 x 221 x 137 = 4373209880

Therefore, the lowest common multiple of 628,920,221,548 is 4373209880.

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.

628 x 920 x 221 x 548 = 69971358080

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.

628 : 1, 2, 4, 157, 314, 628

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

221 : 1, 13, 17, 221

548 : 1, 2, 4, 137, 274, 548

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,920,221,548, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

920:2x 2x 2x 5x 23

221:13x 17

548:2x 2x 137

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

2x 2x 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 69971358080/(1x16)

LCM = 69971358080/16

LCM = 4373209880

Thus, we can understand that the LCM of 628,920,221,548 is 4373209880.
