Given numbers are 756,406,609,812

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

The LCM of 756,406,609,812 is 21924.

Find LCM of 756,406,609,812 with Prime Factorization

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

2 x 2 x 3 x 7 x 29 x 9 x 1 x 1 x 1 = 21924

Therefore, the lowest common multiple of 756,406,609,812 is 21924.

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.

756 x 406 x 609 x 812 = 151782307488

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.

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

406 : 1, 2, 7, 14, 29, 58, 203, 406

609 : 1, 3, 7, 21, 29, 87, 203, 609

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

7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,406,609,812, is 7.

Now, the common factors can be found like this.

756:2x 2x 3x 3x 3x 7

406:2x 7x 29

609:3x 7x 29

812:2x 2x 7x 29

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 7x 7x 29x 29 = 989016

Therefore, the value for common factors is 989016.

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 = 151782307488/(7x989016)

LCM = 151782307488/6923112

LCM = 21924

Thus, we can understand that the LCM of 756,406,609,812 is 21924.
