Given numbers are 686,394,794,697

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

The LCM of 686,394,794,697 is 37395007678.

Find LCM of 686,394,794,697 with Prime Factorization

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

2 x 343 x 197 x 397 x 697 = 37395007678

Therefore, the lowest common multiple of 686,394,794,697 is 37395007678.

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.

686 x 394 x 794 x 697 = 149580030712

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.

686 : 1, 2, 7, 14, 49, 98, 343, 686

394 : 1, 2, 197, 394

794 : 1, 2, 397, 794

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,394,794,697, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

394:2x 197

794:2x 397

697:17x 41

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 149580030712/(1x4)

LCM = 149580030712/4

LCM = 37395007678

Thus, we can understand that the LCM of 686,394,794,697 is 37395007678.
