Given numbers are 783,720,172,348,617

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

The LCM of 783,720,172,348,617 is 1661901840.

Find LCM of 783,720,172,348,617 with Prime Factorization

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

2 x 2 x 3 x 3 x 29 x 3 x 20 x 43 x 1 x 617 = 1661901840

Therefore, the lowest common multiple of 783,720,172,348,617 is 1661901840.

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.

783 x 720 x 172 x 348 x 617 = 20820306251520

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.

783 : 1, 3, 9, 27, 29, 87, 261, 783

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

172 : 1, 2, 4, 43, 86, 172

348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348

617 : 1, 617

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,720,172,348,617, is 1.

Now, the common factors can be found like this.

783:3x 3x 3x 29

720:2x 2x 2x 2x 3x 3x 5

172:2x 2x 43

348:2x 2x 3x 29

617:617

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 2x 3x 3x 3x 29 = 12528

Therefore, the value for common factors is 12528.

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 = 20820306251520/(1x12528)

LCM = 20820306251520/12528

LCM = 1661901840

Thus, we can understand that the LCM of 783,720,172,348,617 is 1661901840.
