Given numbers are 782,412,121,423

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

The LCM of 782,412,121,423 is 8245171836.

Find LCM of 782,412,121,423 with Prime Factorization

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

2 x 391 x 206 x 121 x 423 = 8245171836

Therefore, the lowest common multiple of 782,412,121,423 is 8245171836.

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.

782 x 412 x 121 x 423 = 16490343672

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.

782 : 1, 2, 17, 23, 34, 46, 391, 782

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

121 : 1, 11, 121

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,412,121,423, is 1.

Now, the common factors can be found like this.

782:2x 17x 23

412:2x 2x 103

121:11x 11

423:3x 3x 47

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 = 16490343672/(1x2)

LCM = 16490343672/2

LCM = 8245171836

Thus, we can understand that the LCM of 782,412,121,423 is 8245171836.
