Given numbers are 431,810,193,158

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

The LCM of 431,810,193,158 is 5322880170.

Find LCM of 431,810,193,158 with Prime Factorization

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

2 x 431 x 405 x 193 x 79 = 5322880170

Therefore, the lowest common multiple of 431,810,193,158 is 5322880170.

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.

431 x 810 x 193 x 158 = 10645760340

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.

431 : 1, 431

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

193 : 1, 193

158 : 1, 2, 79, 158

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,810,193,158, is 1.

Now, the common factors can be found like this.

431:431

810:2x 3x 3x 3x 3x 5

193:193

158:2x 79

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 = 10645760340/(1x2)

LCM = 10645760340/2

LCM = 5322880170

Thus, we can understand that the LCM of 431,810,193,158 is 5322880170.
