Given numbers are 804,642,857,756

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

The LCM of 804,642,857,756 is 4644737748.

Find LCM of 804,642,857,756 with Prime Factorization

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

2 x 2 x 3 x 67 x 107 x 857 x 63 = 4644737748

Therefore, the lowest common multiple of 804,642,857,756 is 4644737748.

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.

804 x 642 x 857 x 756 = 334421117856

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.

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

642 : 1, 2, 3, 6, 107, 214, 321, 642

857 : 1, 857

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,642,857,756, is 1.

Now, the common factors can be found like this.

804:2x 2x 3x 67

642:2x 3x 107

857:857

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

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 3 = 72

Therefore, the value for common factors is 72.

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 = 334421117856/(1x72)

LCM = 334421117856/72

LCM = 4644737748

Thus, we can understand that the LCM of 804,642,857,756 is 4644737748.
