Find LCM of 837,819,683,208,620 with Prime Factorization
| 2 | 837, 819, 683, 208, 620 |
| 2 | 837, 819, 683, 104, 310 |
| 3 | 837, 819, 683, 52, 155 |
| 3 | 279, 273, 683, 52, 155 |
| 13 | 93, 91, 683, 52, 155 |
| 31 | 93, 7, 683, 4, 155 |
| 3, 7, 683, 4, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 13 x 31 x 3 x 7 x 683 x 4 x 5 = 4161764880
Therefore, the lowest common multiple of 837,819,683,208,620 is 4161764880.
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.
837 x 819 x 683 x 208 x 620 = 60378884879040
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.
837 : 1, 3, 9, 27, 31, 93, 279, 837
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
683 : 1, 683
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 837,819,683,208,620, is 1.
Now, the common factors can be found like this.
837:3x 3x 3x 31
819:3x 3x 7x 13
683:683
208:2x 2x 2x 2x 13
620:2x 2x 5x 31
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 13x 31 = 14508
Therefore, the value for common factors is 14508.
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 = 60378884879040/(1x14508)
LCM = 60378884879040/14508
LCM = 4161764880
Thus, we can understand that the LCM of 837,819,683,208,620 is 4161764880.
