Find LCM of 972,918,850,449 with Prime Factorization
| 2 | 972, 918, 850, 449 |
| 3 | 486, 459, 425, 449 |
| 3 | 162, 153, 425, 449 |
| 3 | 54, 51, 425, 449 |
| 17 | 18, 17, 425, 449 |
| 18, 1, 25, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 17 x 18 x 1 x 25 x 449 = 185481900
Therefore, the lowest common multiple of 972,918,850,449 is 185481900.
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.
972 x 918 x 850 x 449 = 340544768400
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
449 : 1, 449
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,918,850,449, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
918:2x 3x 3x 3x 17
850:2x 5x 5x 17
449:449
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 17 = 1836
Therefore, the value for common factors is 1836.
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 = 340544768400/(1x1836)
LCM = 340544768400/1836
LCM = 185481900
Thus, we can understand that the LCM of 972,918,850,449 is 185481900.
