Find LCM of 275,450,972,916,689 with Prime Factorization
| 2 | 275, 450, 972, 916, 689 |
| 2 | 275, 225, 486, 458, 689 |
| 3 | 275, 225, 243, 229, 689 |
| 3 | 275, 75, 81, 229, 689 |
| 5 | 275, 25, 27, 229, 689 |
| 5 | 55, 5, 27, 229, 689 |
| 11, 1, 27, 229, 689 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 5 x 11 x 1 x 27 x 229 x 689 = 42174861300
Therefore, the lowest common multiple of 275,450,972,916,689 is 42174861300.
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.
275 x 450 x 972 x 916 x 689 = 75914750340000
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.
275 : 1, 5, 11, 25, 55, 275
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
916 : 1, 2, 4, 229, 458, 916
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 275,450,972,916,689, is 1.
Now, the common factors can be found like this.
275:5x 5x 11
450:2x 3x 3x 5x 5
972:2x 2x 3x 3x 3x 3x 3
916:2x 2x 229
689:13x 53
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 3x 3x 5x 5 = 1800
Therefore, the value for common factors is 1800.
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 = 75914750340000/(1x1800)
LCM = 75914750340000/1800
LCM = 42174861300
Thus, we can understand that the LCM of 275,450,972,916,689 is 42174861300.
