Given numbers are 728,793,816,853,394

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

The LCM of 728,793,816,853,394 is 761161202256.

Find LCM of 728,793,816,853,394 with Prime Factorization

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

2 x 2 x 2 x 13 x 7 x 61 x 102 x 853 x 197 = 761161202256

Therefore, the lowest common multiple of 728,793,816,853,394 is 761161202256.

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.

728 x 793 x 816 x 853 x 394 = 158321530069248

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

793 : 1, 13, 61, 793

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

853 : 1, 853

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,793,816,853,394, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

793:13x 61

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

853:853

394:2x 197

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 13 = 208

Therefore, the value for common factors is 208.

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 = 158321530069248/(1x208)

LCM = 158321530069248/208

LCM = 761161202256

Thus, we can understand that the LCM of 728,793,816,853,394 is 761161202256.
