Find LCM of 690,866,840,984,884 with Prime Factorization
| 2 | 690, 866, 840, 984, 884 |
| 2 | 345, 433, 420, 492, 442 |
| 2 | 345, 433, 210, 246, 221 |
| 3 | 345, 433, 105, 123, 221 |
| 5 | 115, 433, 35, 41, 221 |
| 23, 433, 7, 41, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 23 x 433 x 7 x 41 x 221 = 75800339160
Therefore, the lowest common multiple of 690,866,840,984,884 is 75800339160.
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.
690 x 866 x 840 x 984 x 884 = 436609953561600
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
866 : 1, 2, 433, 866
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
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,866,840,984,884, is 2.
Now, the common factors can be found like this.
690:2x 3x 5x 23
866:2x 433
840:2x 2x 2x 3x 5x 7
984:2x 2x 2x 3x 41
884:2x 2x 13x 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 2x 2x 2x 2x 3x 3x 5 = 2880
Therefore, the value for common factors is 2880.
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 = 436609953561600/(2x2880)
LCM = 436609953561600/5760
LCM = 75800339160
Thus, we can understand that the LCM of 690,866,840,984,884 is 75800339160.
