Given numbers are 331,570,331,698

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

The LCM of 331,570,331,698 is 65845830.

Find LCM of 331,570,331,698 with Prime Factorization

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

2 x 331 x 1 x 285 x 1 x 349 = 65845830

Therefore, the lowest common multiple of 331,570,331,698 is 65845830.

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.

331 x 570 x 331 x 698 = 43589939460

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.

331 : 1, 331

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

331 : 1, 331

698 : 1, 2, 349, 698

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,570,331,698, is 1.

Now, the common factors can be found like this.

331:331

570:2x 3x 5x 19

331:331

698:2x 349

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

2x 331 = 662

Therefore, the value for common factors is 662.

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 = 43589939460/(1x662)

LCM = 43589939460/662

LCM = 65845830

Thus, we can understand that the LCM of 331,570,331,698 is 65845830.
