Given numbers are 385,880,770,455

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

The LCM of 385,880,770,455 is 80080.

Find LCM of 385,880,770,455 with Prime Factorization

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

2 x 5 x 7 x 11 x 1 x 8 x 1 x 13 = 80080

Therefore, the lowest common multiple of 385,880,770,455 is 80080.

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.

385 x 880 x 770 x 455 = 118698580000

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.

385 : 1, 5, 7, 11, 35, 55, 77, 385

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

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

455 : 1, 5, 7, 13, 35, 65, 91, 455

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,880,770,455, is 5.

Now, the common factors can be found like this.

385:5x 7x 11

880:2x 2x 2x 2x 5x 11

770:2x 5x 7x 11

455:5x 7x 13

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

2x 5x 5x 7x 7x 11x 11 = 296450

Therefore, the value for common factors is 296450.

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 = 118698580000/(5x296450)

LCM = 118698580000/1482250

LCM = 80080

Thus, we can understand that the LCM of 385,880,770,455 is 80080.
