Given numbers are 605,900,140,880

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

The LCM of 605,900,140,880 is 3049200.

Find LCM of 605,900,140,880 with Prime Factorization

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

2 x 2 x 5 x 11 x 11 x 45 x 7 x 4 = 3049200

Therefore, the lowest common multiple of 605,900,140,880 is 3049200.

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.

605 x 900 x 140 x 880 = 67082400000

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.

605 : 1, 5, 11, 55, 121, 605

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,900,140,880, is 5.

Now, the common factors can be found like this.

605:5x 11x 11

900:2x 2x 3x 3x 5x 5

140:2x 2x 5x 7

880:2x 2x 2x 2x 5x 11

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 5x 5x 11 = 4400

Therefore, the value for common factors is 4400.

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 = 67082400000/(5x4400)

LCM = 67082400000/22000

LCM = 3049200

Thus, we can understand that the LCM of 605,900,140,880 is 3049200.
