Given numbers are 655,991,505,457

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

The LCM of 655,991,505,457 is 29960739485.

Find LCM of 655,991,505,457 with Prime Factorization

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

5 x 131 x 991 x 101 x 457 = 29960739485

Therefore, the lowest common multiple of 655,991,505,457 is 29960739485.

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.

655 x 991 x 505 x 457 = 149803697425

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.

655 : 1, 5, 131, 655

991 : 1, 991

505 : 1, 5, 101, 505

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,991,505,457, is 1.

Now, the common factors can be found like this.

655:5x 131

991:991

505:5x 101

457:457

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

5 = 5

Therefore, the value for common factors is 5.

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 = 149803697425/(1x5)

LCM = 149803697425/5

LCM = 29960739485

Thus, we can understand that the LCM of 655,991,505,457 is 29960739485.
