Calculate the LCM of 217,391,477,755,696

Given numbers are 217,391,477,755,696

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

The LCM of 217,391,477,755,696 is 7089078848040.

Find LCM of 217,391,477,755,696 with Prime Factorization


3 217, 391, 477, 755, 696
217, 391, 159, 755, 232

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

3 x 217 x 391 x 159 x 755 x 232 = 7089078848040

Therefore, the lowest common multiple of 217,391,477,755,696 is 7089078848040.

LCM Formula to Find Lowest Common Multiple of 217,391,477,755,696

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 391 x 477 x 755 x 696 = 21267236544120

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

391 : 1, 17, 23, 391

477 : 1, 3, 9, 53, 159, 477

755 : 1, 5, 151, 755

696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,391,477,755,696, is 1.

Now, the common factors can be found like this.

217:7x 31

391:17x 23

477:3x 3x 53

755:5x 151

696:2x 2x 2x 3x 29

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 = 21267236544120/(1x3)

LCM = 21267236544120/3

LCM = 7089078848040

Thus, we can understand that the LCM of 217,391,477,755,696 is 7089078848040.
