Find LCM of 972,410,783,918 with Prime Factorization
| 2 | 972, 410, 783, 918 |
| 3 | 486, 205, 783, 459 |
| 3 | 162, 205, 261, 153 |
| 3 | 54, 205, 87, 51 |
| 18, 205, 29, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 18 x 205 x 29 x 17 = 98235180
Therefore, the lowest common multiple of 972,410,783,918 is 98235180.
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 410 x 783 x 918 = 286453784880
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
410 : 1, 2, 5, 10, 41, 82, 205, 410
783 : 1, 3, 9, 27, 29, 87, 261, 783
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,410,783,918, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
410:2x 5x 41
783:3x 3x 3x 29
918:2x 3x 3x 3x 17
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 3x 3x 3 = 2916
Therefore, the value for common factors is 2916.
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 = 286453784880/(1x2916)
LCM = 286453784880/2916
LCM = 98235180
Thus, we can understand that the LCM of 972,410,783,918 is 98235180.
