Given numbers are 865,931,794,397

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

The LCM of 865,931,794,397 is 639420110.

Find LCM of 865,931,794,397 with Prime Factorization

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

397 x 865 x 931 x 2 x 1 = 639420110

Therefore, the lowest common multiple of 865,931,794,397 is 639420110.

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.

865 x 931 x 794 x 397 = 253849783670

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.

865 : 1, 5, 173, 865

931 : 1, 7, 19, 49, 133, 931

794 : 1, 2, 397, 794

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,931,794,397, is 1.

Now, the common factors can be found like this.

865:5x 173

931:7x 7x 19

794:2x 397

397:397

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

397 = 397

Therefore, the value for common factors is 397.

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 = 253849783670/(1x397)

LCM = 253849783670/397

LCM = 639420110

Thus, we can understand that the LCM of 865,931,794,397 is 639420110.
