Given numbers are 411,128,138,343

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

The LCM of 411,128,138,343 is 415024512.

Find LCM of 411,128,138,343 with Prime Factorization

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

2 x 3 x 137 x 64 x 23 x 343 = 415024512

Therefore, the lowest common multiple of 411,128,138,343 is 415024512.

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.

411 x 128 x 138 x 343 = 2490147072

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.

411 : 1, 3, 137, 411

128 : 1, 2, 4, 8, 16, 32, 64, 128

138 : 1, 2, 3, 6, 23, 46, 69, 138

343 : 1, 7, 49, 343

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,128,138,343, is 1.

Now, the common factors can be found like this.

411:3x 137

128:2x 2x 2x 2x 2x 2x 2

138:2x 3x 23

343:7x 7x 7

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 2490147072/(1x6)

LCM = 2490147072/6

LCM = 415024512

Thus, we can understand that the LCM of 411,128,138,343 is 415024512.
