Given numbers are 821,520,812,652

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

The LCM of 821,520,812,652 is 14126355880.

Find LCM of 821,520,812,652 with Prime Factorization

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

2 x 2 x 821 x 130 x 203 x 163 = 14126355880

Therefore, the lowest common multiple of 821,520,812,652 is 14126355880.

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.

821 x 520 x 812 x 652 = 226021694080

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.

821 : 1, 821

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,520,812,652, is 1.

Now, the common factors can be found like this.

821:821

520:2x 2x 2x 5x 13

812:2x 2x 7x 29

652:2x 2x 163

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 2 = 16

Therefore, the value for common factors is 16.

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 = 226021694080/(1x16)

LCM = 226021694080/16

LCM = 14126355880

Thus, we can understand that the LCM of 821,520,812,652 is 14126355880.
