Find LCM of 840,529,978,845,798 with Prime Factorization
| 2 | 840, 529, 978, 845, 798 |
| 3 | 420, 529, 489, 845, 399 |
| 5 | 140, 529, 163, 845, 133 |
| 7 | 28, 529, 163, 169, 133 |
| 4, 529, 163, 169, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 4 x 529 x 163 x 169 x 19 = 232574913480
Therefore, the lowest common multiple of 840,529,978,845,798 is 232574913480.
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.
840 x 529 x 978 x 845 x 798 = 293044390984800
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.
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
529 : 1, 23, 529
978 : 1, 2, 3, 6, 163, 326, 489, 978
845 : 1, 5, 13, 65, 169, 845
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,529,978,845,798, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
529:23x 23
978:2x 3x 163
845:5x 13x 13
798:2x 3x 7x 19
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 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 293044390984800/(1x1260)
LCM = 293044390984800/1260
LCM = 232574913480
Thus, we can understand that the LCM of 840,529,978,845,798 is 232574913480.
