Given numbers are 788,544,342,872,670

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

The LCM of 788,544,342,872,670 is 669163957920.

Find LCM of 788,544,342,872,670 with Prime Factorization

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

2 x 2 x 2 x 197 x 68 x 171 x 109 x 335 = 669163957920

Therefore, the lowest common multiple of 788,544,342,872,670 is 669163957920.

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.

788 x 544 x 342 x 872 x 670 = 85652986613760

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.

788 : 1, 2, 4, 197, 394, 788

544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

872 : 1, 2, 4, 8, 109, 218, 436, 872

670 : 1, 2, 5, 10, 67, 134, 335, 670

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,544,342,872,670, is 2.

Now, the common factors can be found like this.

788:2x 2x 197

544:2x 2x 2x 2x 2x 17

342:2x 3x 3x 19

872:2x 2x 2x 109

670:2x 5x 67

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 2x 2 = 64

Therefore, the value for common factors is 64.

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 = 85652986613760/(2x64)

LCM = 85652986613760/128

LCM = 669163957920

Thus, we can understand that the LCM of 788,544,342,872,670 is 669163957920.
