Given numbers are 645,772,560,445

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

The LCM of 645,772,560,445 is 1240866480.

Find LCM of 645,772,560,445 with Prime Factorization

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

2 x 2 x 5 x 129 x 193 x 28 x 89 = 1240866480

Therefore, the lowest common multiple of 645,772,560,445 is 1240866480.

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.

645 x 772 x 560 x 445 = 124086648000

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.

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

772 : 1, 2, 4, 193, 386, 772

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,772,560,445, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

772:2x 2x 193

560:2x 2x 2x 2x 5x 7

445:5x 89

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 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 124086648000/(1x100)

LCM = 124086648000/100

LCM = 1240866480

Thus, we can understand that the LCM of 645,772,560,445 is 1240866480.
