Given numbers are 686,171,277,554

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

The LCM of 686,171,277,554 is 32493762.

Find LCM of 686,171,277,554 with Prime Factorization

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

2 x 277 x 343 x 171 x 1 x 1 = 32493762

Therefore, the lowest common multiple of 686,171,277,554 is 32493762.

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 171 x 277 x 554 = 18001544148

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

171 : 1, 3, 9, 19, 57, 171

277 : 1, 277

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,171,277,554, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

171:3x 3x 19

277:277

554:2x 277

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

2x 277 = 554

Therefore, the value for common factors is 554.

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 = 18001544148/(1x554)

LCM = 18001544148/554

LCM = 32493762

Thus, we can understand that the LCM of 686,171,277,554 is 32493762.
