Find LCM of 693,951,429,162,221 with Prime Factorization
| 3 | 693, 951, 429, 162, 221 |
| 3 | 231, 317, 143, 54, 221 |
| 11 | 77, 317, 143, 18, 221 |
| 13 | 7, 317, 13, 18, 221 |
| 7, 317, 1, 18, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 13 x 7 x 317 x 1 x 18 x 17 = 873891018
Therefore, the lowest common multiple of 693,951,429,162,221 is 873891018.
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.
693 x 951 x 429 x 162 x 221 = 10122279661494
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
951 : 1, 3, 317, 951
429 : 1, 3, 11, 13, 33, 39, 143, 429
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,951,429,162,221, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
951:3x 317
429:3x 11x 13
162:2x 3x 3x 3x 3
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.
3x 3x 3x 3x 11x 13 = 11583
Therefore, the value for common factors is 11583.
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 = 10122279661494/(1x11583)
LCM = 10122279661494/11583
LCM = 873891018
Thus, we can understand that the LCM of 693,951,429,162,221 is 873891018.
