Given numbers are 621,203,161,296,860

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

The LCM of 621,203,161,296,860 is 8022649320.

Find LCM of 621,203,161,296,860 with Prime Factorization

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

2 x 2 x 7 x 23 x 27 x 29 x 1 x 74 x 215 = 8022649320

Therefore, the lowest common multiple of 621,203,161,296,860 is 8022649320.

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.

621 x 203 x 161 x 296 x 860 = 5166586162080

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.

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

203 : 1, 7, 29, 203

161 : 1, 7, 23, 161

296 : 1, 2, 4, 8, 37, 74, 148, 296

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,203,161,296,860, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

203:7x 29

161:7x 23

296:2x 2x 2x 37

860:2x 2x 5x 43

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 7x 23 = 644

Therefore, the value for common factors is 644.

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 = 5166586162080/(1x644)

LCM = 5166586162080/644

LCM = 8022649320

Thus, we can understand that the LCM of 621,203,161,296,860 is 8022649320.
