Given numbers are 621,177,645,777

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

The LCM of 621,177,645,777 is 2040242715.

Find LCM of 621,177,645,777 with Prime Factorization

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

3 x 207 x 59 x 215 x 259 = 2040242715

Therefore, the lowest common multiple of 621,177,645,777 is 2040242715.

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.

621 x 177 x 645 x 777 = 55086553305

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.

621 : 1, 3, 9, 23, 27, 69, 207, 621

177 : 1, 3, 59, 177

645 : 1, 3, 5, 15, 43, 129, 215, 645

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

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,177,645,777, is 3.

Now, the common factors can be found like this.

621:3x 3x 3x 23

177:3x 59

645:3x 5x 43

777:3x 7x 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 3 = 9

Therefore, the value for common factors is 9.

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 = 55086553305/(3x9)

LCM = 55086553305/27

LCM = 2040242715

Thus, we can understand that the LCM of 621,177,645,777 is 2040242715.
