Given numbers are 686,520,241,241

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

The LCM of 686,520,241,241 is 42984760.

Find LCM of 686,520,241,241 with Prime Factorization

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

2 x 241 x 343 x 260 x 1 x 1 = 42984760

Therefore, the lowest common multiple of 686,520,241,241 is 42984760.

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 520 x 241 x 241 = 20718654320

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

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

241 : 1, 241

241 : 1, 241

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,520,241,241, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

520:2x 2x 2x 5x 13

241:241

241:241

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

2x 241 = 482

Therefore, the value for common factors is 482.

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 = 20718654320/(1x482)

LCM = 20718654320/482

LCM = 42984760

Thus, we can understand that the LCM of 686,520,241,241 is 42984760.
