Given numbers are 686,968,811

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

The LCM of 686,968,811 is 269271464.

Find LCM of 686,968,811 with Prime Factorization

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

2 x 343 x 484 x 811 = 269271464

Therefore, the lowest common multiple of 686,968,811 is 269271464.

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 968 x 811 = 538542928

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

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

811 : 1, 811

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,968,811, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

968:2x 2x 2x 11x 11

811:811

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

2 = 2

Therefore, the value for common factors is 2.

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 = 538542928/(1x2)

LCM = 538542928/2

LCM = 269271464

Thus, we can understand that the LCM of 686,968,811 is 269271464.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 212, 539, 122
• LCM of 533, 109, 509
