Given numbers are 688,622,621,161

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

The LCM of 688,622,621,161 is 930118896.

Find LCM of 688,622,621,161 with Prime Factorization

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

2 x 23 x 344 x 311 x 27 x 7 = 930118896

Therefore, the lowest common multiple of 688,622,621,161 is 930118896.

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 622 x 621 x 161 = 42785469216

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

622 : 1, 2, 311, 622

621 : 1, 3, 9, 23, 27, 69, 207, 621

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,622,621,161, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

622:2x 311

621:3x 3x 3x 23

161:7x 23

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 42785469216/(1x46)

LCM = 42785469216/46

LCM = 930118896

Thus, we can understand that the LCM of 688,622,621,161 is 930118896.
