Given numbers are 770,491,677,161,406

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

The LCM of 770,491,677,161,406 is 170720911130.

Find LCM of 770,491,677,161,406 with Prime Factorization

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

2 x 7 x 55 x 491 x 677 x 23 x 29 = 170720911130

Therefore, the lowest common multiple of 770,491,677,161,406 is 170720911130.

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.

770 x 491 x 677 x 161 x 406 = 16730649290740

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.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

491 : 1, 491

677 : 1, 677

161 : 1, 7, 23, 161

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,491,677,161,406, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

491:491

677:677

161:7x 23

406:2x 7x 29

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

2x 7x 7 = 98

Therefore, the value for common factors is 98.

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 = 16730649290740/(1x98)

LCM = 16730649290740/98

LCM = 170720911130

Thus, we can understand that the LCM of 770,491,677,161,406 is 170720911130.
