Given numbers are 605,816,186,630

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

The LCM of 605,816,186,630 is 321385680.

Find LCM of 605,816,186,630 with Prime Factorization

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

2 x 3 x 5 x 121 x 136 x 31 x 21 = 321385680

Therefore, the lowest common multiple of 605,816,186,630 is 321385680.

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 816 x 186 x 630 = 57849422400

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

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

186 : 1, 2, 3, 6, 31, 62, 93, 186

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,816,186,630, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

816:2x 2x 2x 2x 3x 17

186:2x 3x 31

630:2x 3x 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.

2x 2x 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 57849422400/(1x180)

LCM = 57849422400/180

LCM = 321385680

Thus, we can understand that the LCM of 605,816,186,630 is 321385680.
