Given numbers are 217,620,113,221

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

The LCM of 217,620,113,221 is 108382820.

Find LCM of 217,620,113,221 with Prime Factorization

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

31 x 7 x 20 x 113 x 221 = 108382820

Therefore, the lowest common multiple of 217,620,113,221 is 108382820.

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.

217 x 620 x 113 x 221 = 3359867420

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.

217 : 1, 7, 31, 217

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

113 : 1, 113

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,620,113,221, is 1.

Now, the common factors can be found like this.

217:7x 31

620:2x 2x 5x 31

113:113

221:13x 17

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

31 = 31

Therefore, the value for common factors is 31.

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 = 3359867420/(1x31)

LCM = 3359867420/31

LCM = 108382820

Thus, we can understand that the LCM of 217,620,113,221 is 108382820.
