Given numbers are 221,905,496,628

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

The LCM of 221,905,496,628 is 15574789360.

Find LCM of 221,905,496,628 with Prime Factorization

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

2 x 2 x 221 x 905 x 124 x 157 = 15574789360

Therefore, the lowest common multiple of 221,905,496,628 is 15574789360.

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 905 x 496 x 628 = 62299157440

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

905 : 1, 5, 181, 905

496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496

628 : 1, 2, 4, 157, 314, 628

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,905,496,628, is 1.

Now, the common factors can be found like this.

221:13x 17

905:5x 181

496:2x 2x 2x 2x 31

628:2x 2x 157

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 = 62299157440/(1x4)

LCM = 62299157440/4

LCM = 15574789360

Thus, we can understand that the LCM of 221,905,496,628 is 15574789360.
