Given numbers are 680,970,485,734,645

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

The LCM of 680,970,485,734,645 is 3122744280.

Find LCM of 680,970,485,734,645 with Prime Factorization

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

2 x 5 x 97 x 68 x 1 x 1 x 367 x 129 = 3122744280

Therefore, the lowest common multiple of 680,970,485,734,645 is 3122744280.

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.

680 x 970 x 485 x 734 x 645 = 151453097580000

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.

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

970 : 1, 2, 5, 10, 97, 194, 485, 970

485 : 1, 5, 97, 485

734 : 1, 2, 367, 734

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,970,485,734,645, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

970:2x 5x 97

485:5x 97

734:2x 367

645:3x 5x 43

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 5x 5x 97 = 48500

Therefore, the value for common factors is 48500.

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 = 151453097580000/(1x48500)

LCM = 151453097580000/48500

LCM = 3122744280

Thus, we can understand that the LCM of 680,970,485,734,645 is 3122744280.
