Given numbers are 428,247,792,555,165

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

The LCM of 428,247,792,555,165 is 3872377080.

Find LCM of 428,247,792,555,165 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 107 x 247 x 6 x 37 x 1 = 3872377080

Therefore, the lowest common multiple of 428,247,792,555,165 is 3872377080.

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.

428 x 247 x 792 x 555 x 165 = 7667306618400

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.

428 : 1, 2, 4, 107, 214, 428

247 : 1, 13, 19, 247

792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792

555 : 1, 3, 5, 15, 37, 111, 185, 555

165 : 1, 3, 5, 11, 15, 33, 55, 165

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,247,792,555,165, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

247:13x 19

792:2x 2x 2x 3x 3x 11

555:3x 5x 37

165:3x 5x 11

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 3x 3x 5x 11 = 1980

Therefore, the value for common factors is 1980.

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 = 7667306618400/(1x1980)

LCM = 7667306618400/1980

LCM = 3872377080

Thus, we can understand that the LCM of 428,247,792,555,165 is 3872377080.
