Given numbers are 169,221,977

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

The LCM of 169,221,977 is 2806921.

Find LCM of 169,221,977 with Prime Factorization

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

13 x 13 x 17 x 977 = 2806921

Therefore, the lowest common multiple of 169,221,977 is 2806921.

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.

169 x 221 x 977 = 36489973

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.

169 : 1, 13, 169

221 : 1, 13, 17, 221

977 : 1, 977

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,221,977, is 1.

Now, the common factors can be found like this.

169:13x 13

221:13x 17

977:977

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

13 = 13

Therefore, the value for common factors is 13.

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 = 36489973/(1x13)

LCM = 36489973/13

LCM = 2806921

Thus, we can understand that the LCM of 169,221,977 is 2806921.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 379, 352, 536
• LCM of 707, 227, 673
