Given numbers are 923,771,157,221

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

The LCM of 923,771,157,221 is 1899348477.

Find LCM of 923,771,157,221 with Prime Factorization

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

13 x 71 x 771 x 157 x 17 = 1899348477

Therefore, the lowest common multiple of 923,771,157,221 is 1899348477.

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.

923 x 771 x 157 x 221 = 24691530201

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.

923 : 1, 13, 71, 923

771 : 1, 3, 257, 771

157 : 1, 157

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,771,157,221, is 1.

Now, the common factors can be found like this.

923:13x 71

771:3x 257

157:157

221:13x 17

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 = 24691530201/(1x13)

LCM = 24691530201/13

LCM = 1899348477

Thus, we can understand that the LCM of 923,771,157,221 is 1899348477.
