Given numbers are 615,689,203,128,579

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

The LCM of 615,689,203,128,579 is 2124993736320.

Find LCM of 615,689,203,128,579 with Prime Factorization

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

3 x 205 x 689 x 203 x 128 x 193 = 2124993736320

Therefore, the lowest common multiple of 615,689,203,128,579 is 2124993736320.

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.

615 x 689 x 203 x 128 x 579 = 6374981208960

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.

615 : 1, 3, 5, 15, 41, 123, 205, 615

689 : 1, 13, 53, 689

203 : 1, 7, 29, 203

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

579 : 1, 3, 193, 579

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,689,203,128,579, is 1.

Now, the common factors can be found like this.

615:3x 5x 41

689:13x 53

203:7x 29

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

579:3x 193

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

3 = 3

Therefore, the value for common factors is 3.

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 = 6374981208960/(1x3)

LCM = 6374981208960/3

LCM = 2124993736320

Thus, we can understand that the LCM of 615,689,203,128,579 is 2124993736320.
