Given numbers are 423,138,412,434

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

The LCM of 423,138,412,434 is 869811516.

Find LCM of 423,138,412,434 with Prime Factorization

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

2 x 3 x 141 x 23 x 206 x 217 = 869811516

Therefore, the lowest common multiple of 423,138,412,434 is 869811516.

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.

423 x 138 x 412 x 434 = 10437738192

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.

423 : 1, 3, 9, 47, 141, 423

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

412 : 1, 2, 4, 103, 206, 412

434 : 1, 2, 7, 14, 31, 62, 217, 434

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,138,412,434, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

138:2x 3x 23

412:2x 2x 103

434:2x 7x 31

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 = 10437738192/(1x12)

LCM = 10437738192/12

LCM = 869811516

Thus, we can understand that the LCM of 423,138,412,434 is 869811516.
