Given numbers are 397,265,817,929,760

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

The LCM of 397,265,817,929,760 is 638798868520.

Find LCM of 397,265,817,929,760 with Prime Factorization

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

5 x 19 x 397 x 53 x 43 x 929 x 8 = 638798868520

Therefore, the lowest common multiple of 397,265,817,929,760 is 638798868520.

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 265 x 817 x 929 x 760 = 60685892509400

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

265 : 1, 5, 53, 265

817 : 1, 19, 43, 817

929 : 1, 929

760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,265,817,929,760, is 1.

Now, the common factors can be found like this.

397:397

265:5x 53

817:19x 43

929:929

760:2x 2x 2x 5x 19

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

5x 19 = 95

Therefore, the value for common factors is 95.

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 = 60685892509400/(1x95)

LCM = 60685892509400/95

LCM = 638798868520

Thus, we can understand that the LCM of 397,265,817,929,760 is 638798868520.
