Given numbers are 618,990,920,338

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

The LCM of 618,990,920,338 is 1585429560.

Find LCM of 618,990,920,338 with Prime Factorization

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

2 x 3 x 5 x 103 x 33 x 92 x 169 = 1585429560

Therefore, the lowest common multiple of 618,990,920,338 is 1585429560.

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.

618 x 990 x 920 x 338 = 190251547200

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.

618 : 1, 2, 3, 6, 103, 206, 309, 618

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

338 : 1, 2, 13, 26, 169, 338

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,990,920,338, is 2.

Now, the common factors can be found like this.

618:2x 3x 103

990:2x 3x 3x 5x 11

920:2x 2x 2x 5x 23

338:2x 13x 13

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 5 = 60

Therefore, the value for common factors is 60.

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 = 190251547200/(2x60)

LCM = 190251547200/120

LCM = 1585429560

Thus, we can understand that the LCM of 618,990,920,338 is 1585429560.
