Given numbers are 781,388,669,669

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

The LCM of 781,388,669,669 is 202725732.

Find LCM of 781,388,669,669 with Prime Factorization

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

3 x 223 x 781 x 388 x 1 x 1 = 202725732

Therefore, the lowest common multiple of 781,388,669,669 is 202725732.

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.

781 x 388 x 669 x 669 = 135623514708

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.

781 : 1, 11, 71, 781

388 : 1, 2, 4, 97, 194, 388

669 : 1, 3, 223, 669

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,388,669,669, is 1.

Now, the common factors can be found like this.

781:11x 71

388:2x 2x 97

669:3x 223

669:3x 223

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

3x 223 = 669

Therefore, the value for common factors is 669.

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 = 135623514708/(1x669)

LCM = 135623514708/669

LCM = 202725732

Thus, we can understand that the LCM of 781,388,669,669 is 202725732.
