Given numbers are 198,418,720,826

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

The LCM of 198,418,720,826 is 62148240.

Find LCM of 198,418,720,826 with Prime Factorization

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

2 x 3 x 3 x 11 x 1 x 19 x 40 x 413 = 62148240

Therefore, the lowest common multiple of 198,418,720,826 is 62148240.

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.

198 x 418 x 720 x 826 = 49221406080

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.

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

418 : 1, 2, 11, 19, 22, 38, 209, 418

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

826 : 1, 2, 7, 14, 59, 118, 413, 826

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,418,720,826, is 2.

Now, the common factors can be found like this.

198:2x 3x 3x 11

418:2x 11x 19

720:2x 2x 2x 2x 3x 3x 5

826:2x 7x 59

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 3x 3x 11 = 396

Therefore, the value for common factors is 396.

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 = 49221406080/(2x396)

LCM = 49221406080/792

LCM = 62148240

Thus, we can understand that the LCM of 198,418,720,826 is 62148240.
