Given numbers are 501,909,221,220

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

The LCM of 501,909,221,220 is 7380661860.

Find LCM of 501,909,221,220 with Prime Factorization

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

3 x 167 x 303 x 221 x 220 = 7380661860

Therefore, the lowest common multiple of 501,909,221,220 is 7380661860.

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.

501 x 909 x 221 x 220 = 22141985580

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.

501 : 1, 3, 167, 501

909 : 1, 3, 9, 101, 303, 909

221 : 1, 13, 17, 221

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 501,909,221,220, is 1.

Now, the common factors can be found like this.

501:3x 167

909:3x 3x 101

221:13x 17

220:2x 2x 5x 11

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

3 = 3

Therefore, the value for common factors is 3.

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 = 22141985580/(1x3)

LCM = 22141985580/3

LCM = 7380661860

Thus, we can understand that the LCM of 501,909,221,220 is 7380661860.
