Given numbers are 623,826,744,689

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

The LCM of 623,826,744,689 is 18842226312.

Find LCM of 623,826,744,689 with Prime Factorization

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

2 x 7 x 89 x 59 x 372 x 689 = 18842226312

Therefore, the lowest common multiple of 623,826,744,689 is 18842226312.

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.

623 x 826 x 744 x 689 = 263791168368

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.

623 : 1, 7, 89, 623

826 : 1, 2, 7, 14, 59, 118, 413, 826

744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,826,744,689, is 1.

Now, the common factors can be found like this.

623:7x 89

826:2x 7x 59

744:2x 2x 2x 3x 31

689:13x 53

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 263791168368/(1x14)

LCM = 263791168368/14

LCM = 18842226312

Thus, we can understand that the LCM of 623,826,744,689 is 18842226312.
