Given numbers are 736,688,691

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

The LCM of 736,688,691 is 21868768.

Find LCM of 736,688,691 with Prime Factorization

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

2 x 2 x 2 x 2 x 46 x 43 x 691 = 21868768

Therefore, the lowest common multiple of 736,688,691 is 21868768.

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.

736 x 688 x 691 = 349900288

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.

736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736

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

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 736,688,691, is 1.

Now, the common factors can be found like this.

736:2x 2x 2x 2x 2x 23

688:2x 2x 2x 2x 43

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.

2x 2x 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 349900288/(1x16)

LCM = 349900288/16

LCM = 21868768

Thus, we can understand that the LCM of 736,688,691 is 21868768.
