Find LCM of 621,322,391,954,157 with Prime Factorization
| 2 | 621, 322, 391, 954, 157 |
| 3 | 621, 161, 391, 477, 157 |
| 3 | 207, 161, 391, 159, 157 |
| 23 | 69, 161, 391, 53, 157 |
| 3, 7, 17, 53, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 23 x 3 x 7 x 17 x 53 x 157 = 1229827158
Therefore, the lowest common multiple of 621,322,391,954,157 is 1229827158.
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.
621 x 322 x 391 x 954 x 157 = 11710414198476
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
322 : 1, 2, 7, 14, 23, 46, 161, 322
391 : 1, 17, 23, 391
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
157 : 1, 157
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,322,391,954,157, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
322:2x 7x 23
391:17x 23
954:2x 3x 3x 53
157:157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 23x 23 = 9522
Therefore, the value for common factors is 9522.
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 = 11710414198476/(1x9522)
LCM = 11710414198476/9522
LCM = 1229827158
Thus, we can understand that the LCM of 621,322,391,954,157 is 1229827158.
