Given numbers are 684,245,481,816

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

The LCM of 684,245,481,816 is 5481206640.

Find LCM of 684,245,481,816 with Prime Factorization

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

2 x 2 x 3 x 57 x 245 x 481 x 68 = 5481206640

Therefore, the lowest common multiple of 684,245,481,816 is 5481206640.

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.

684 x 245 x 481 x 816 = 65774479680

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.

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

245 : 1, 5, 7, 35, 49, 245

481 : 1, 13, 37, 481

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,245,481,816, is 1.

Now, the common factors can be found like this.

684:2x 2x 3x 3x 19

245:5x 7x 7

481:13x 37

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

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 3 = 12

Therefore, the value for common factors is 12.

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 = 65774479680/(1x12)

LCM = 65774479680/12

LCM = 5481206640

Thus, we can understand that the LCM of 684,245,481,816 is 5481206640.
