Calculate the LCM of 122,942,408,409

Given numbers are 122,942,408,409

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

The LCM of 122,942,408,409 is 1598133144.

Find LCM of 122,942,408,409 with Prime Factorization


2 122, 942, 408, 409
3 61, 471, 204, 409
61, 157, 68, 409

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

2 x 3 x 61 x 157 x 68 x 409 = 1598133144

Therefore, the lowest common multiple of 122,942,408,409 is 1598133144.

LCM Formula to Find Lowest Common Multiple of 122,942,408,409

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 942 x 408 x 409 = 19177597728

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

942 : 1, 2, 3, 6, 157, 314, 471, 942

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,942,408,409, is 1.

Now, the common factors can be found like this.

122:2x 61

942:2x 3x 157

408:2x 2x 2x 3x 17

409:409

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 3 = 12

Therefore, the value for common factors is 12.

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 = 19177597728/(1x12)

LCM = 19177597728/12

LCM = 1598133144

Thus, we can understand that the LCM of 122,942,408,409 is 1598133144.
