Given numbers are 816,652,705,782,621

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

The LCM of 816,652,705,782,621 is 6470174160.

Find LCM of 816,652,705,782,621 with Prime Factorization

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

2 x 2 x 3 x 17 x 23 x 4 x 163 x 235 x 1 x 9 = 6470174160

Therefore, the lowest common multiple of 816,652,705,782,621 is 6470174160.

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.

816 x 652 x 705 x 782 x 621 = 182148342952320

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.

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

652 : 1, 2, 4, 163, 326, 652

705 : 1, 3, 5, 15, 47, 141, 235, 705

782 : 1, 2, 17, 23, 34, 46, 391, 782

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 816,652,705,782,621, is 1.

Now, the common factors can be found like this.

816:2x 2x 2x 2x 3x 17

652:2x 2x 163

705:3x 5x 47

782:2x 17x 23

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 2x 3x 3x 17x 23 = 28152

Therefore, the value for common factors is 28152.

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 = 182148342952320/(1x28152)

LCM = 182148342952320/28152

LCM = 6470174160

Thus, we can understand that the LCM of 816,652,705,782,621 is 6470174160.
