Given numbers are 644,193,537,608,668

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

The LCM of 644,193,537,608,668 is 1694250104736.

Find LCM of 644,193,537,608,668 with Prime Factorization

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

2 x 2 x 161 x 193 x 537 x 152 x 167 = 1694250104736

Therefore, the lowest common multiple of 644,193,537,608,668 is 1694250104736.

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.

644 x 193 x 537 x 608 x 668 = 27108001675776

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

193 : 1, 193

537 : 1, 3, 179, 537

608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,193,537,608,668, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

193:193

537:3x 179

608:2x 2x 2x 2x 2x 19

668:2x 2x 167

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 = 27108001675776/(1x16)

LCM = 27108001675776/16

LCM = 1694250104736

Thus, we can understand that the LCM of 644,193,537,608,668 is 1694250104736.
