Given numbers are 820,777,437,703,163
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,777,437,703,163 is 45384119340.
Find LCM of 820,777,437,703,163 with Prime Factorization
| 19 | 820, 777, 437, 703, 163 |
| 37 | 820, 777, 23, 37, 163 |
| 820, 21, 23, 1, 163 |
Multiply the prime numbers at the bottom and the left side.
19 x 37 x 820 x 21 x 23 x 1 x 163 = 45384119340
Therefore, the lowest common multiple of 820,777,437,703,163 is 45384119340.
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.
820 x 777 x 437 x 703 x 163 = 31905035896020
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
777 : 1, 3, 7, 21, 37, 111, 259, 777
437 : 1, 19, 23, 437
703 : 1, 19, 37, 703
163 : 1, 163
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,777,437,703,163, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
777:3x 7x 37
437:19x 23
703:19x 37
163:163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 37 = 703
Therefore, the value for common factors is 703.
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 = 31905035896020/(1x703)
LCM = 31905035896020/703
LCM = 45384119340
Thus, we can understand that the LCM of 820,777,437,703,163 is 45384119340.
