Given numbers are 638,674,424,106,205

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

The LCM of 638,674,424,106,205 is 9344160760.

Find LCM of 638,674,424,106,205 with Prime Factorization

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

2 x 53 x 319 x 337 x 4 x 1 x 205 = 9344160760

Therefore, the lowest common multiple of 638,674,424,106,205 is 9344160760.

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.

638 x 674 x 424 x 106 x 205 = 3961924162240

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

674 : 1, 2, 337, 674

424 : 1, 2, 4, 8, 53, 106, 212, 424

106 : 1, 2, 53, 106

205 : 1, 5, 41, 205

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,674,424,106,205, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

674:2x 337

424:2x 2x 2x 53

106:2x 53

205:5x 41

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 53 = 424

Therefore, the value for common factors is 424.

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 = 3961924162240/(1x424)

LCM = 3961924162240/424

LCM = 9344160760

Thus, we can understand that the LCM of 638,674,424,106,205 is 9344160760.
