Given numbers are 122,780,702,526,442

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

The LCM of 122,780,702,526,442 is 1914571620.

Find LCM of 122,780,702,526,442 with Prime Factorization

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

2 x 3 x 13 x 61 x 10 x 9 x 263 x 17 = 1914571620

Therefore, the lowest common multiple of 122,780,702,526,442 is 1914571620.

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 702 x 526 x 442 = 15531004981440

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

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

526 : 1, 2, 263, 526

442 : 1, 2, 13, 17, 26, 34, 221, 442

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,780,702,526,442, is 2.

Now, the common factors can be found like this.

122:2x 61

780:2x 2x 3x 5x 13

702:2x 3x 3x 3x 13

526:2x 263

442:2x 13x 17

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 3x 13x 13 = 4056

Therefore, the value for common factors is 4056.

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 = 15531004981440/(2x4056)

LCM = 15531004981440/8112

LCM = 1914571620

Thus, we can understand that the LCM of 122,780,702,526,442 is 1914571620.
