Given numbers are 221,532,226,545

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

The LCM of 221,532,226,545 is 7240671620.

Find LCM of 221,532,226,545 with Prime Factorization

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

2 x 221 x 266 x 113 x 545 = 7240671620

Therefore, the lowest common multiple of 221,532,226,545 is 7240671620.

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 532 x 226 x 545 = 14481343240

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

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

226 : 1, 2, 113, 226

545 : 1, 5, 109, 545

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,532,226,545, is 1.

Now, the common factors can be found like this.

221:13x 17

532:2x 2x 7x 19

226:2x 113

545:5x 109

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

2 = 2

Therefore, the value for common factors is 2.

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 = 14481343240/(1x2)

LCM = 14481343240/2

LCM = 7240671620

Thus, we can understand that the LCM of 221,532,226,545 is 7240671620.
