Given numbers are 622,108,780,728

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

The LCM of 622,108,780,728 is 30565080.

Find LCM of 622,108,780,728 with Prime Factorization

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

2 x 2 x 3 x 13 x 311 x 9 x 5 x 14 = 30565080

Therefore, the lowest common multiple of 622,108,780,728 is 30565080.

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.

622 x 108 x 780 x 728 = 38145219840

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.

622 : 1, 2, 311, 622

108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,108,780,728, is 2.

Now, the common factors can be found like this.

622:2x 311

108:2x 2x 3x 3x 3

780:2x 2x 3x 5x 13

728:2x 2x 2x 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 2x 2x 2x 3x 13 = 624

Therefore, the value for common factors is 624.

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 = 38145219840/(2x624)

LCM = 38145219840/1248

LCM = 30565080

Thus, we can understand that the LCM of 622,108,780,728 is 30565080.
