Find LCM of 221,436,939,128,264 with Prime Factorization
| 2 | 221, 436, 939, 128, 264 |
| 2 | 221, 218, 939, 64, 132 |
| 2 | 221, 109, 939, 32, 66 |
| 3 | 221, 109, 939, 16, 33 |
| 221, 109, 313, 16, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 221 x 109 x 313 x 16 x 11 = 31848355968
Therefore, the lowest common multiple of 221,436,939,128,264 is 31848355968.
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.
221 x 436 x 939 x 128 x 264 = 3057442172928
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.
221 : 1, 13, 17, 221
436 : 1, 2, 4, 109, 218, 436
939 : 1, 3, 313, 939
128 : 1, 2, 4, 8, 16, 32, 64, 128
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,436,939,128,264, is 1.
Now, the common factors can be found like this.
221:13x 17
436:2x 2x 109
939:3x 313
128:2x 2x 2x 2x 2x 2x 2
264:2x 2x 2x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 3 = 96
Therefore, the value for common factors is 96.
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 = 3057442172928/(1x96)
LCM = 3057442172928/96
LCM = 31848355968
Thus, we can understand that the LCM of 221,436,939,128,264 is 31848355968.
