Given numbers are 427,637,221,889

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

The LCM of 427,637,221,889 is 83892263.

Find LCM of 427,637,221,889 with Prime Factorization

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

7 x 13 x 61 x 7 x 17 x 127 = 83892263

Therefore, the lowest common multiple of 427,637,221,889 is 83892263.

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.

427 x 637 x 221 x 889 = 53439371531

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.

427 : 1, 7, 61, 427

637 : 1, 7, 13, 49, 91, 637

221 : 1, 13, 17, 221

889 : 1, 7, 127, 889

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,637,221,889, is 1.

Now, the common factors can be found like this.

427:7x 61

637:7x 7x 13

221:13x 17

889:7x 127

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

7x 7x 13 = 637

Therefore, the value for common factors is 637.

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 = 53439371531/(1x637)

LCM = 53439371531/637

LCM = 83892263

Thus, we can understand that the LCM of 427,637,221,889 is 83892263.
