Find LCM of 843,962,689,820,860 with Prime Factorization
| 2 | 843, 962, 689, 820, 860 |
| 2 | 843, 481, 689, 410, 430 |
| 5 | 843, 481, 689, 205, 215 |
| 13 | 843, 481, 689, 41, 43 |
| 843, 37, 53, 41, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 843 x 37 x 53 x 41 x 43 = 757758520740
Therefore, the lowest common multiple of 843,962,689,820,860 is 757758520740.
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.
843 x 962 x 689 x 820 x 860 = 394034430784800
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.
843 : 1, 3, 281, 843
962 : 1, 2, 13, 26, 37, 74, 481, 962
689 : 1, 13, 53, 689
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,962,689,820,860, is 1.
Now, the common factors can be found like this.
843:3x 281
962:2x 13x 37
689:13x 53
820:2x 2x 5x 41
860:2x 2x 5x 43
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 5x 13 = 520
Therefore, the value for common factors is 520.
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 = 394034430784800/(1x520)
LCM = 394034430784800/520
LCM = 757758520740
Thus, we can understand that the LCM of 843,962,689,820,860 is 757758520740.
