Calculate the LCM of 168,777,417,555

Given numbers are 168,777,417,555

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

The LCM of 168,777,417,555 is 4320120.

Find LCM of 168,777,417,555 with Prime Factorization


3 168, 777, 417, 555
7 56, 259, 139, 185
37 8, 37, 139, 185
8, 1, 139, 5

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

3 x 7 x 37 x 8 x 1 x 139 x 5 = 4320120

Therefore, the lowest common multiple of 168,777,417,555 is 4320120.

LCM Formula to Find Lowest Common Multiple of 168,777,417,555

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.

168 x 777 x 417 x 555 = 30210599160

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.

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

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

417 : 1, 3, 139, 417

555 : 1, 3, 5, 15, 37, 111, 185, 555

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,777,417,555, is 3.

Now, the common factors can be found like this.

168:2x 2x 2x 3x 7

777:3x 7x 37

417:3x 139

555:3x 5x 37

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

3x 3x 7x 37 = 2331

Therefore, the value for common factors is 2331.

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 = 30210599160/(3x2331)

LCM = 30210599160/6993

LCM = 4320120

Thus, we can understand that the LCM of 168,777,417,555 is 4320120.
