Given numbers are 921,228,665,201

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

The LCM of 921,228,665,201 is 164140620.

Find LCM of 921,228,665,201 with Prime Factorization

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

3 x 19 x 307 x 4 x 35 x 67 = 164140620

Therefore, the lowest common multiple of 921,228,665,201 is 164140620.

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.

921 x 228 x 665 x 201 = 28068046020

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.

921 : 1, 3, 307, 921

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

665 : 1, 5, 7, 19, 35, 95, 133, 665

201 : 1, 3, 67, 201

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,228,665,201, is 1.

Now, the common factors can be found like this.

921:3x 307

228:2x 2x 3x 19

665:5x 7x 19

201:3x 67

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

3x 3x 19 = 171

Therefore, the value for common factors is 171.

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 = 28068046020/(1x171)

LCM = 28068046020/171

LCM = 164140620

Thus, we can understand that the LCM of 921,228,665,201 is 164140620.
