Given numbers are 782,822,791,689

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

The LCM of 782,822,791,689 is 175163768598.

Find LCM of 782,822,791,689 with Prime Factorization

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

2 x 391 x 411 x 791 x 689 = 175163768598

Therefore, the lowest common multiple of 782,822,791,689 is 175163768598.

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.

782 x 822 x 791 x 689 = 350327537196

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.

782 : 1, 2, 17, 23, 34, 46, 391, 782

822 : 1, 2, 3, 6, 137, 274, 411, 822

791 : 1, 7, 113, 791

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,822,791,689, is 1.

Now, the common factors can be found like this.

782:2x 17x 23

822:2x 3x 137

791:7x 113

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.

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 = 350327537196/(1x2)

LCM = 350327537196/2

LCM = 175163768598

Thus, we can understand that the LCM of 782,822,791,689 is 175163768598.
