Given numbers are 397,865,470,855,901

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

The LCM of 397,865,470,855,901 is 4973422664970.

Find LCM of 397,865,470,855,901 with Prime Factorization

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

5 x 397 x 173 x 94 x 171 x 901 = 4973422664970

Therefore, the lowest common multiple of 397,865,470,855,901 is 4973422664970.

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.

397 x 865 x 470 x 855 x 901 = 124335566624250

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.

397 : 1, 397

865 : 1, 5, 173, 865

470 : 1, 2, 5, 10, 47, 94, 235, 470

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

901 : 1, 17, 53, 901

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,865,470,855,901, is 1.

Now, the common factors can be found like this.

397:397

865:5x 173

470:2x 5x 47

855:3x 3x 5x 19

901:17x 53

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 = 124335566624250/(1x25)

LCM = 124335566624250/25

LCM = 4973422664970

Thus, we can understand that the LCM of 397,865,470,855,901 is 4973422664970.
