Given numbers are 671,661,221,247

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

The LCM of 671,661,221,247 is 1862386669.

Find LCM of 671,661,221,247 with Prime Factorization

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

13 x 671 x 661 x 17 x 19 = 1862386669

Therefore, the lowest common multiple of 671,661,221,247 is 1862386669.

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 661 x 221 x 247 = 24211026697

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

661 : 1, 661

221 : 1, 13, 17, 221

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,661,221,247, is 1.

Now, the common factors can be found like this.

671:11x 61

661:661

221:13x 17

247:13x 19

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

13 = 13

Therefore, the value for common factors is 13.

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 = 24211026697/(1x13)

LCM = 24211026697/13

LCM = 1862386669

Thus, we can understand that the LCM of 671,661,221,247 is 1862386669.
