Given numbers are 840,326,326,122

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

The LCM of 840,326,326,122 is 8352120.

Find LCM of 840,326,326,122 with Prime Factorization

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

2 x 163 x 420 x 1 x 1 x 61 = 8352120

Therefore, the lowest common multiple of 840,326,326,122 is 8352120.

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.

840 x 326 x 326 x 122 = 10891164480

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.

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

326 : 1, 2, 163, 326

326 : 1, 2, 163, 326

122 : 1, 2, 61, 122

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,326,326,122, is 2.

Now, the common factors can be found like this.

840:2x 2x 2x 3x 5x 7

326:2x 163

326:2x 163

122:2x 61

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 163 = 652

Therefore, the value for common factors is 652.

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 = 10891164480/(2x652)

LCM = 10891164480/1304

LCM = 8352120

Thus, we can understand that the LCM of 840,326,326,122 is 8352120.
