Given numbers are 515,661,664,270,122

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

The LCM of 515,661,664,270,122 is 372280567320.

Find LCM of 515,661,664,270,122 with Prime Factorization

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

2 x 5 x 103 x 661 x 332 x 27 x 61 = 372280567320

Therefore, the lowest common multiple of 515,661,664,270,122 is 372280567320.

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.

515 x 661 x 664 x 270 x 122 = 7445611346400

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.

515 : 1, 5, 103, 515

661 : 1, 661

664 : 1, 2, 4, 8, 83, 166, 332, 664

270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,661,664,270,122, is 1.

Now, the common factors can be found like this.

515:5x 103

661:661

664:2x 2x 2x 83

270:2x 3x 3x 3x 5

122:2x 61

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 5 = 20

Therefore, the value for common factors is 20.

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 = 7445611346400/(1x20)

LCM = 7445611346400/20

LCM = 372280567320

Thus, we can understand that the LCM of 515,661,664,270,122 is 372280567320.
