Find LCM of 901,216,985,972,489 with Prime Factorization
| 2 | 901, 216, 985, 972, 489 |
| 2 | 901, 108, 985, 486, 489 |
| 3 | 901, 54, 985, 243, 489 |
| 3 | 901, 18, 985, 81, 163 |
| 3 | 901, 6, 985, 27, 163 |
| 901, 2, 985, 9, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 901 x 2 x 985 x 9 x 163 = 281219146920
Therefore, the lowest common multiple of 901,216,985,972,489 is 281219146920.
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.
901 x 216 x 985 x 972 x 489 = 91115003602080
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.
901 : 1, 17, 53, 901
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
985 : 1, 5, 197, 985
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,216,985,972,489, is 1.
Now, the common factors can be found like this.
901:17x 53
216:2x 2x 2x 3x 3x 3
985:5x 197
972:2x 2x 3x 3x 3x 3x 3
489:3x 163
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 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 91115003602080/(1x324)
LCM = 91115003602080/324
LCM = 281219146920
Thus, we can understand that the LCM of 901,216,985,972,489 is 281219146920.
