Given numbers are 612,208,540,198,644

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

The LCM of 612,208,540,198,644 is 845404560.

Find LCM of 612,208,540,198,644 with Prime Factorization

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

2 x 2 x 3 x 3 x 17 x 52 x 15 x 11 x 161 = 845404560

Therefore, the lowest common multiple of 612,208,540,198,644 is 845404560.

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.

612 x 208 x 540 x 198 x 644 = 8765154478080

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.

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

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

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,208,540,198,644, is 2.

Now, the common factors can be found like this.

612:2x 2x 3x 3x 17

208:2x 2x 2x 2x 13

540:2x 2x 3x 3x 3x 5

198:2x 3x 3x 11

644:2x 2x 7x 23

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 2x 2x 2x 2x 3x 3x 3x 3 = 5184

Therefore, the value for common factors is 5184.

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 = 8765154478080/(2x5184)

LCM = 8765154478080/10368

LCM = 845404560

Thus, we can understand that the LCM of 612,208,540,198,644 is 845404560.
