Given numbers are 273,689,921,789

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

The LCM of 273,689,921,789 is 1168241529.

Find LCM of 273,689,921,789 with Prime Factorization

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

3 x 13 x 7 x 53 x 307 x 263 = 1168241529

Therefore, the lowest common multiple of 273,689,921,789 is 1168241529.

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.

273 x 689 x 921 x 789 = 136684258893

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.

273 : 1, 3, 7, 13, 21, 39, 91, 273

689 : 1, 13, 53, 689

921 : 1, 3, 307, 921

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 273,689,921,789, is 1.

Now, the common factors can be found like this.

273:3x 7x 13

689:13x 53

921:3x 307

789:3x 263

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3x 13 = 117

Therefore, the value for common factors is 117.

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 = 136684258893/(1x117)

LCM = 136684258893/117

LCM = 1168241529

Thus, we can understand that the LCM of 273,689,921,789 is 1168241529.
