Given numbers are 515,667,128,309

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

The LCM of 515,667,128,309 is 131905920.

Find LCM of 515,667,128,309 with Prime Factorization

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

103 x 5 x 667 x 128 x 3 = 131905920

Therefore, the lowest common multiple of 515,667,128,309 is 131905920.

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 667 x 128 x 309 = 13586309760

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

667 : 1, 23, 29, 667

128 : 1, 2, 4, 8, 16, 32, 64, 128

309 : 1, 3, 103, 309

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,667,128,309, is 1.

Now, the common factors can be found like this.

515:5x 103

667:23x 29

128:2x 2x 2x 2x 2x 2x 2

309:3x 103

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

103 = 103

Therefore, the value for common factors is 103.

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 = 13586309760/(1x103)

LCM = 13586309760/103

LCM = 131905920

Thus, we can understand that the LCM of 515,667,128,309 is 131905920.
