Given numbers are 688,161,331,862,211

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

The LCM of 688,161,331,862,211 is 3334279739728.

Find LCM of 688,161,331,862,211 with Prime Factorization

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

2 x 344 x 161 x 331 x 431 x 211 = 3334279739728

Therefore, the lowest common multiple of 688,161,331,862,211 is 3334279739728.

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.

688 x 161 x 331 x 862 x 211 = 6668559479456

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

161 : 1, 7, 23, 161

331 : 1, 331

862 : 1, 2, 431, 862

211 : 1, 211

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,161,331,862,211, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

161:7x 23

331:331

862:2x 431

211:211

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 = 6668559479456/(1x2)

LCM = 6668559479456/2

LCM = 3334279739728

Thus, we can understand that the LCM of 688,161,331,862,211 is 3334279739728.
