The LCM of 705,188,820,943 is 2659260.
Find LCM of 705,188,820,943 with Prime Factorization
| 2 | 705, 188, 820, 943 |
| 2 | 705, 94, 410, 943 |
| 5 | 705, 47, 205, 943 |
| 41 | 141, 47, 41, 943 |
| 47 | 141, 47, 1, 23 |
| 3, 1, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 41 x 47 x 3 x 1 x 1 x 23 = 2659260
Therefore, the lowest common multiple of 705,188,820,943 is 2659260.
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.
705 x 188 x 820 x 943 = 102487880400
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
188 : 1, 2, 4, 47, 94, 188
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,188,820,943, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
188:2x 2x 47
820:2x 2x 5x 41
943:23x 41
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 5x 41x 47 = 38540
Therefore, the value for common factors is 38540.
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 = 102487880400/(1x38540)
LCM = 102487880400/38540
LCM = 2659260
Thus, we can understand that the LCM of 705,188,820,943 is 2659260.
