Given numbers are 731,668,346,455

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

The LCM of 731,668,346,455 is 38437164220.

Find LCM of 731,668,346,455 with Prime Factorization

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

2 x 731 x 334 x 173 x 455 = 38437164220

Therefore, the lowest common multiple of 731,668,346,455 is 38437164220.

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.

731 x 668 x 346 x 455 = 76874328440

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.

731 : 1, 17, 43, 731

668 : 1, 2, 4, 167, 334, 668

346 : 1, 2, 173, 346

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,668,346,455, is 1.

Now, the common factors can be found like this.

731:17x 43

668:2x 2x 167

346:2x 173

455:5x 7x 13

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

2 = 2

Therefore, the value for common factors is 2.

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 = 76874328440/(1x2)

LCM = 76874328440/2

LCM = 38437164220

Thus, we can understand that the LCM of 731,668,346,455 is 38437164220.
