Find LCM of 204,693,669,840,985 with Prime Factorization
| 2 | 204, 693, 669, 840, 985 |
| 2 | 102, 693, 669, 420, 985 |
| 3 | 51, 693, 669, 210, 985 |
| 5 | 17, 231, 223, 70, 985 |
| 7 | 17, 231, 223, 14, 197 |
| 17, 33, 223, 2, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 17 x 33 x 223 x 2 x 197 = 20702044440
Therefore, the lowest common multiple of 204,693,669,840,985 is 20702044440.
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.
204 x 693 x 669 x 840 x 985 = 78253727983200
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.
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
669 : 1, 3, 223, 669
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 204,693,669,840,985, is 1.
Now, the common factors can be found like this.
204:2x 2x 3x 17
693:3x 3x 7x 11
669:3x 223
840:2x 2x 2x 3x 5x 7
985:5x 197
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 5x 7 = 3780
Therefore, the value for common factors is 3780.
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 = 78253727983200/(1x3780)
LCM = 78253727983200/3780
LCM = 20702044440
Thus, we can understand that the LCM of 204,693,669,840,985 is 20702044440.
