Given numbers are 861,634,720,163,302

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

The LCM of 861,634,720,163,302 is 1612271611440.

Find LCM of 861,634,720,163,302 with Prime Factorization

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

2 x 3 x 287 x 317 x 120 x 163 x 151 = 1612271611440

Therefore, the lowest common multiple of 861,634,720,163,302 is 1612271611440.

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.

861 x 634 x 720 x 163 x 302 = 19347259337280

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

634 : 1, 2, 317, 634

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

163 : 1, 163

302 : 1, 2, 151, 302

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,634,720,163,302, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

634:2x 317

720:2x 2x 2x 2x 3x 3x 5

163:163

302:2x 151

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 3 = 12

Therefore, the value for common factors is 12.

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 = 19347259337280/(1x12)

LCM = 19347259337280/12

LCM = 1612271611440

Thus, we can understand that the LCM of 861,634,720,163,302 is 1612271611440.
