Given numbers are 689,461,481,555

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

The LCM of 689,461,481,555 is 176284095.

Find LCM of 689,461,481,555 with Prime Factorization

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

13 x 37 x 53 x 461 x 1 x 15 = 176284095

Therefore, the lowest common multiple of 689,461,481,555 is 176284095.

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.

689 x 461 x 481 x 555 = 84792649695

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.

689 : 1, 13, 53, 689

461 : 1, 461

481 : 1, 13, 37, 481

555 : 1, 3, 5, 15, 37, 111, 185, 555

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,461,481,555, is 1.

Now, the common factors can be found like this.

689:13x 53

461:461

481:13x 37

555:3x 5x 37

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

13x 37 = 481

Therefore, the value for common factors is 481.

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 = 84792649695/(1x481)

LCM = 84792649695/481

LCM = 176284095

Thus, we can understand that the LCM of 689,461,481,555 is 176284095.
