Given numbers are 665,439,400,972

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

The LCM of 665,439,400,972 is 5675216400.

Find LCM of 665,439,400,972 with Prime Factorization

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

2 x 2 x 5 x 133 x 439 x 20 x 243 = 5675216400

Therefore, the lowest common multiple of 665,439,400,972 is 5675216400.

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.

665 x 439 x 400 x 972 = 113504328000

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

439 : 1, 439

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,439,400,972, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

439:439

400:2x 2x 2x 2x 5x 5

972:2x 2x 3x 3x 3x 3x 3

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 5 = 20

Therefore, the value for common factors is 20.

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 = 113504328000/(1x20)

LCM = 113504328000/20

LCM = 5675216400

Thus, we can understand that the LCM of 665,439,400,972 is 5675216400.
