Given numbers are 645,611,695,485

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

The LCM of 645,611,695,485 is 5313582885.

Find LCM of 645,611,695,485 with Prime Factorization

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

5 x 129 x 611 x 139 x 97 = 5313582885

Therefore, the lowest common multiple of 645,611,695,485 is 5313582885.

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 611 x 695 x 485 = 132839572125

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

611 : 1, 13, 47, 611

695 : 1, 5, 139, 695

485 : 1, 5, 97, 485

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,611,695,485, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

611:13x 47

695:5x 139

485:5x 97

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 132839572125/(1x25)

LCM = 132839572125/25

LCM = 5313582885

Thus, we can understand that the LCM of 645,611,695,485 is 5313582885.
