Find LCM of 821,917,321,216,664 with Prime Factorization
| 2 | 821, 917, 321, 216, 664 |
| 2 | 821, 917, 321, 108, 332 |
| 2 | 821, 917, 321, 54, 166 |
| 3 | 821, 917, 321, 27, 83 |
| 821, 917, 107, 9, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 821 x 917 x 107 x 9 x 83 = 1444202571672
Therefore, the lowest common multiple of 821,917,321,216,664 is 1444202571672.
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.
821 x 917 x 321 x 216 x 664 = 34660861720128
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.
821 : 1, 821
917 : 1, 7, 131, 917
321 : 1, 3, 107, 321
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,917,321,216,664, is 1.
Now, the common factors can be found like this.
821:821
917:7x 131
321:3x 107
216:2x 2x 2x 3x 3x 3
664:2x 2x 2x 83
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 3 = 24
Therefore, the value for common factors is 24.
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 = 34660861720128/(1x24)
LCM = 34660861720128/24
LCM = 1444202571672
Thus, we can understand that the LCM of 821,917,321,216,664 is 1444202571672.
