Given numbers are 128,722,190,714

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

The LCM of 128,722,190,714 is 82481280.

Find LCM of 128,722,190,714 with Prime Factorization

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

2 x 19 x 64 x 19 x 5 x 357 = 82481280

Therefore, the lowest common multiple of 128,722,190,714 is 82481280.

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.

128 x 722 x 190 x 714 = 12537154560

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.

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

722 : 1, 2, 19, 38, 361, 722

190 : 1, 2, 5, 10, 19, 38, 95, 190

714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,722,190,714, is 2.

Now, the common factors can be found like this.

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

722:2x 19x 19

190:2x 5x 19

714:2x 3x 7x 17

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 19 = 76

Therefore, the value for common factors is 76.

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 = 12537154560/(2x76)

LCM = 12537154560/152

LCM = 82481280

Thus, we can understand that the LCM of 128,722,190,714 is 82481280.
