Given numbers are 804,704,720,643

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

The LCM of 804,704,720,643 is 1364806080.

Find LCM of 804,704,720,643 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 67 x 44 x 15 x 643 = 1364806080

Therefore, the lowest common multiple of 804,704,720,643 is 1364806080.

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 704 x 720 x 643 = 262042767360

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

704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,704,720,643, is 1.

Now, the common factors can be found like this.

804:2x 2x 3x 67

704:2x 2x 2x 2x 2x 2x 11

720:2x 2x 2x 2x 3x 3x 5

643:643

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 2x 2x 2x 3 = 192

Therefore, the value for common factors is 192.

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 = 262042767360/(1x192)

LCM = 262042767360/192

LCM = 1364806080

Thus, we can understand that the LCM of 804,704,720,643 is 1364806080.
