Given numbers are 686,817,269,320,521

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

The LCM of 686,817,269,320,521 is 12567710214080.

Find LCM of 686,817,269,320,521 with Prime Factorization

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

2 x 343 x 817 x 269 x 160 x 521 = 12567710214080

Therefore, the lowest common multiple of 686,817,269,320,521 is 12567710214080.

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 817 x 269 x 320 x 521 = 25135420428160

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

817 : 1, 19, 43, 817

269 : 1, 269

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,817,269,320,521, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

817:19x 43

269:269

320:2x 2x 2x 2x 2x 2x 5

521:521

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 = 25135420428160/(1x2)

LCM = 25135420428160/2

LCM = 12567710214080

Thus, we can understand that the LCM of 686,817,269,320,521 is 12567710214080.
