Given numbers are 920,742,406,523

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

The LCM of 920,742,406,523 is 5176800440.

Find LCM of 920,742,406,523 with Prime Factorization

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

2 x 7 x 460 x 53 x 29 x 523 = 5176800440

Therefore, the lowest common multiple of 920,742,406,523 is 5176800440.

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.

920 x 742 x 406 x 523 = 144950412320

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

742 : 1, 2, 7, 14, 53, 106, 371, 742

406 : 1, 2, 7, 14, 29, 58, 203, 406

523 : 1, 523

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,742,406,523, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

742:2x 7x 53

406:2x 7x 29

523:523

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 7 = 28

Therefore, the value for common factors is 28.

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 = 144950412320/(1x28)

LCM = 144950412320/28

LCM = 5176800440

Thus, we can understand that the LCM of 920,742,406,523 is 5176800440.
