Given numbers are 660,622,840,305,774

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

The LCM of 660,622,840,305,774 is 22612673160.

Find LCM of 660,622,840,305,774 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 311 x 14 x 61 x 129 = 22612673160

Therefore, the lowest common multiple of 660,622,840,305,774 is 22612673160.

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.

660 x 622 x 840 x 305 x 774 = 81405623376000

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

622 : 1, 2, 311, 622

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

305 : 1, 5, 61, 305

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,622,840,305,774, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

622:2x 311

840:2x 2x 2x 3x 5x 7

305:5x 61

774:2x 3x 3x 43

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 3x 5x 5 = 3600

Therefore, the value for common factors is 3600.

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 = 81405623376000/(1x3600)

LCM = 81405623376000/3600

LCM = 22612673160

Thus, we can understand that the LCM of 660,622,840,305,774 is 22612673160.
