Given numbers are 774,406,390,977

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

The LCM of 774,406,390,977 is 9978032610.

Find LCM of 774,406,390,977 with Prime Factorization

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

2 x 3 x 129 x 203 x 65 x 977 = 9978032610

Therefore, the lowest common multiple of 774,406,390,977 is 9978032610.

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.

774 x 406 x 390 x 977 = 119736391320

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.

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

406 : 1, 2, 7, 14, 29, 58, 203, 406

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

977 : 1, 977

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,406,390,977, is 1.

Now, the common factors can be found like this.

774:2x 3x 3x 43

406:2x 7x 29

390:2x 3x 5x 13

977:977

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 = 119736391320/(1x12)

LCM = 119736391320/12

LCM = 9978032610

Thus, we can understand that the LCM of 774,406,390,977 is 9978032610.
