Given numbers are 208,217,628,453

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

The LCM of 208,217,628,453 is 3210117456.

Find LCM of 208,217,628,453 with Prime Factorization

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

2 x 2 x 52 x 217 x 157 x 453 = 3210117456

Therefore, the lowest common multiple of 208,217,628,453 is 3210117456.

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.

208 x 217 x 628 x 453 = 12840469824

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.

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

217 : 1, 7, 31, 217

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

453 : 1, 3, 151, 453

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,217,628,453, is 1.

Now, the common factors can be found like this.

208:2x 2x 2x 2x 13

217:7x 31

628:2x 2x 157

453:3x 151

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 12840469824/(1x4)

LCM = 12840469824/4

LCM = 3210117456

Thus, we can understand that the LCM of 208,217,628,453 is 3210117456.
