Given numbers are 221,156,734,403

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

The LCM of 221,156,734,403 is 30171804.

Find LCM of 221,156,734,403 with Prime Factorization

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

2 x 13 x 17 x 6 x 367 x 31 = 30171804

Therefore, the lowest common multiple of 221,156,734,403 is 30171804.

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 156 x 734 x 403 = 10198069752

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

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

734 : 1, 2, 367, 734

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,156,734,403, is 1.

Now, the common factors can be found like this.

221:13x 17

156:2x 2x 3x 13

734:2x 367

403:13x 31

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

2x 13x 13 = 338

Therefore, the value for common factors is 338.

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 = 10198069752/(1x338)

LCM = 10198069752/338

LCM = 30171804

Thus, we can understand that the LCM of 221,156,734,403 is 30171804.
