Given numbers are 221,977,174,122,128

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

The LCM of 221,977,174,122,128 is 146671554432.

Find LCM of 221,977,174,122,128 with Prime Factorization

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

2 x 221 x 977 x 87 x 61 x 64 = 146671554432

Therefore, the lowest common multiple of 221,977,174,122,128 is 146671554432.

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.

221 x 977 x 174 x 122 x 128 = 586686217728

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.

221 : 1, 13, 17, 221

977 : 1, 977

174 : 1, 2, 3, 6, 29, 58, 87, 174

122 : 1, 2, 61, 122

128 : 1, 2, 4, 8, 16, 32, 64, 128

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,977,174,122,128, is 1.

Now, the common factors can be found like this.

221:13x 17

977:977

174:2x 3x 29

122:2x 61

128:2x 2x 2x 2x 2x 2x 2

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 = 586686217728/(1x4)

LCM = 586686217728/4

LCM = 146671554432

Thus, we can understand that the LCM of 221,977,174,122,128 is 146671554432.
