Given numbers are 777,171,920

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

The LCM of 777,171,920 is 40745880.

Find LCM of 777,171,920 with Prime Factorization

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

3 x 259 x 57 x 920 = 40745880

Therefore, the lowest common multiple of 777,171,920 is 40745880.

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.

777 x 171 x 920 = 122237640

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.

777 : 1, 3, 7, 21, 37, 111, 259, 777

171 : 1, 3, 9, 19, 57, 171

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,171,920, is 1.

Now, the common factors can be found like this.

777:3x 7x 37

171:3x 3x 19

920:2x 2x 2x 5x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3 = 3

Therefore, the value for common factors is 3.

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 = 122237640/(1x3)

LCM = 122237640/3

LCM = 40745880

Thus, we can understand that the LCM of 777,171,920 is 40745880.
