Given numbers are 122,711,821,406

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

The LCM of 122,711,821,406 is 14456681946.

Find LCM of 122,711,821,406 with Prime Factorization

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

2 x 61 x 711 x 821 x 203 = 14456681946

Therefore, the lowest common multiple of 122,711,821,406 is 14456681946.

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 711 x 821 x 406 = 28913363892

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

711 : 1, 3, 9, 79, 237, 711

821 : 1, 821

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,711,821,406, is 1.

Now, the common factors can be found like this.

122:2x 61

711:3x 3x 79

821:821

406:2x 7x 29

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 = 28913363892/(1x2)

LCM = 28913363892/2

LCM = 14456681946

Thus, we can understand that the LCM of 122,711,821,406 is 14456681946.
