Given numbers are 671,243,155,217

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

The LCM of 671,243,155,217 is 176912505.

Find LCM of 671,243,155,217 with Prime Factorization

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

31 x 671 x 243 x 5 x 7 = 176912505

Therefore, the lowest common multiple of 671,243,155,217 is 176912505.

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.

671 x 243 x 155 x 217 = 5484287655

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.

671 : 1, 11, 61, 671

243 : 1, 3, 9, 27, 81, 243

155 : 1, 5, 31, 155

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,243,155,217, is 1.

Now, the common factors can be found like this.

671:11x 61

243:3x 3x 3x 3x 3

155:5x 31

217:7x 31

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

31 = 31

Therefore, the value for common factors is 31.

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 = 5484287655/(1x31)

LCM = 5484287655/31

LCM = 176912505

Thus, we can understand that the LCM of 671,243,155,217 is 176912505.
