Given numbers are 628,397,172,161

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

The LCM of 628,397,172,161 is 1726014668.

Find LCM of 628,397,172,161 with Prime Factorization

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

2 x 2 x 157 x 397 x 43 x 161 = 1726014668

Therefore, the lowest common multiple of 628,397,172,161 is 1726014668.

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.

628 x 397 x 172 x 161 = 6904058672

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.

628 : 1, 2, 4, 157, 314, 628

397 : 1, 397

172 : 1, 2, 4, 43, 86, 172

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,397,172,161, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

397:397

172:2x 2x 43

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 2 = 4

Therefore, the value for common factors is 4.

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 = 6904058672/(1x4)

LCM = 6904058672/4

LCM = 1726014668

Thus, we can understand that the LCM of 628,397,172,161 is 1726014668.
