Given numbers are 647,544,998,121,923

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

The LCM of 647,544,998,121,923 is 19615112229856.

Find LCM of 647,544,998,121,923 with Prime Factorization

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

2 x 647 x 272 x 499 x 121 x 923 = 19615112229856

Therefore, the lowest common multiple of 647,544,998,121,923 is 19615112229856.

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.

647 x 544 x 998 x 121 x 923 = 39230224459712

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.

647 : 1, 647

544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544

998 : 1, 2, 499, 998

121 : 1, 11, 121

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,544,998,121,923, is 1.

Now, the common factors can be found like this.

647:647

544:2x 2x 2x 2x 2x 17

998:2x 499

121:11x 11

923:13x 71

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

2 = 2

Therefore, the value for common factors is 2.

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 = 39230224459712/(1x2)

LCM = 39230224459712/2

LCM = 19615112229856

Thus, we can understand that the LCM of 647,544,998,121,923 is 19615112229856.
