Given numbers are 703,123,716,998,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 703,123,716,998,420 is 1081289656860.
Find LCM of 703,123,716,998,420 with Prime Factorization
| 2 | 703, 123, 716, 998, 420 |
| 2 | 703, 123, 358, 499, 210 |
| 3 | 703, 123, 179, 499, 105 |
| 703, 41, 179, 499, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 703 x 41 x 179 x 499 x 35 = 1081289656860
Therefore, the lowest common multiple of 703,123,716,998,420 is 1081289656860.
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.
703 x 123 x 716 x 998 x 420 = 25950951764640
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.
703 : 1, 19, 37, 703
123 : 1, 3, 41, 123
716 : 1, 2, 4, 179, 358, 716
998 : 1, 2, 499, 998
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 703,123,716,998,420, is 1.
Now, the common factors can be found like this.
703:19x 37
123:3x 41
716:2x 2x 179
998:2x 499
420:2x 2x 3x 5x 7
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 3 = 24
Therefore, the value for common factors is 24.
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 = 25950951764640/(1x24)
LCM = 25950951764640/24
LCM = 1081289656860
Thus, we can understand that the LCM of 703,123,716,998,420 is 1081289656860.
