Given numbers are 122,780,734,831,826

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

The LCM of 122,780,734,831,826 is 1997654245860.

Find LCM of 122,780,734,831,826 with Prime Factorization

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

2 x 3 x 61 x 130 x 367 x 277 x 413 = 1997654245860

Therefore, the lowest common multiple of 122,780,734,831,826 is 1997654245860.

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.

122 x 780 x 734 x 831 x 826 = 47943701900640

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.

122 : 1, 2, 61, 122

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

734 : 1, 2, 367, 734

831 : 1, 3, 277, 831

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,780,734,831,826, is 1.

Now, the common factors can be found like this.

122:2x 61

780:2x 2x 3x 5x 13

734:2x 367

831:3x 277

826:2x 7x 59

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 47943701900640/(1x24)

LCM = 47943701900640/24

LCM = 1997654245860

Thus, we can understand that the LCM of 122,780,734,831,826 is 1997654245860.
