Given numbers are 946,545,622,780,621

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

The LCM of 946,545,622,780,621 is 2588886291420.

Find LCM of 946,545,622,780,621 with Prime Factorization

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

2 x 3 x 5 x 473 x 109 x 311 x 26 x 207 = 2588886291420

Therefore, the lowest common multiple of 946,545,622,780,621 is 2588886291420.

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.

946 x 545 x 622 x 780 x 621 = 155333177485200

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.

946 : 1, 2, 11, 22, 43, 86, 473, 946

545 : 1, 5, 109, 545

622 : 1, 2, 311, 622

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

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,545,622,780,621, is 1.

Now, the common factors can be found like this.

946:2x 11x 43

545:5x 109

622:2x 311

780:2x 2x 3x 5x 13

621:3x 3x 3x 23

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 5 = 60

Therefore, the value for common factors is 60.

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 = 155333177485200/(1x60)

LCM = 155333177485200/60

LCM = 2588886291420

Thus, we can understand that the LCM of 946,545,622,780,621 is 2588886291420.
