Given numbers are 115,672,800,639

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

The LCM of 115,672,800,639 is 82303200.

Find LCM of 115,672,800,639 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 3 x 5 x 23 x 7 x 5 x 213 = 82303200

Therefore, the lowest common multiple of 115,672,800,639 is 82303200.

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.

115 x 672 x 800 x 639 = 39505536000

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.

115 : 1, 5, 23, 115

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,672,800,639, is 1.

Now, the common factors can be found like this.

115:5x 23

672:2x 2x 2x 2x 2x 3x 7

800:2x 2x 2x 2x 2x 5x 5

639:3x 3x 71

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 3x 5 = 480

Therefore, the value for common factors is 480.

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 = 39505536000/(1x480)

LCM = 39505536000/480

LCM = 82303200

Thus, we can understand that the LCM of 115,672,800,639 is 82303200.
