Given numbers are 206,874,420

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

The LCM of 206,874,420 is 18904620.

Find LCM of 206,874,420 with Prime Factorization

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

2 x 103 x 437 x 210 = 18904620

Therefore, the lowest common multiple of 206,874,420 is 18904620.

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.

206 x 874 x 420 = 75618480

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.

206 : 1, 2, 103, 206

874 : 1, 2, 19, 23, 38, 46, 437, 874

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 206,874,420, is 2.

Now, the common factors can be found like this.

206:2x 103

874:2x 19x 23

420:2x 2x 3x 5x 7

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 = 75618480/(2x2)

LCM = 75618480/4

LCM = 18904620

Thus, we can understand that the LCM of 206,874,420 is 18904620.
