Given numbers are 662,489,403,638,515

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

The LCM of 662,489,403,638,515 is 21432350686890.

Find LCM of 662,489,403,638,515 with Prime Factorization

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

2 x 331 x 489 x 403 x 319 x 515 = 21432350686890

Therefore, the lowest common multiple of 662,489,403,638,515 is 21432350686890.

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.

662 x 489 x 403 x 638 x 515 = 42864701373780

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.

662 : 1, 2, 331, 662

489 : 1, 3, 163, 489

403 : 1, 13, 31, 403

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

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,489,403,638,515, is 1.

Now, the common factors can be found like this.

662:2x 331

489:3x 163

403:13x 31

638:2x 11x 29

515:5x 103

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

2 = 2

Therefore, the value for common factors is 2.

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 = 42864701373780/(1x2)

LCM = 42864701373780/2

LCM = 21432350686890

Thus, we can understand that the LCM of 662,489,403,638,515 is 21432350686890.
