Given numbers are 688,509,606,691

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

The LCM of 688,509,606,691 is 73320749616.

Find LCM of 688,509,606,691 with Prime Factorization

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

2 x 344 x 509 x 303 x 691 = 73320749616

Therefore, the lowest common multiple of 688,509,606,691 is 73320749616.

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 509 x 606 x 691 = 146641499232

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

509 : 1, 509

606 : 1, 2, 3, 6, 101, 202, 303, 606

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,509,606,691, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

509:509

606:2x 3x 101

691:691

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 = 146641499232/(1x2)

LCM = 146641499232/2

LCM = 73320749616

Thus, we can understand that the LCM of 688,509,606,691 is 73320749616.
