Given numbers are 719,538,703,807,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 719,538,703,807,990 is 134608253670.
Find LCM of 719,538,703,807,990 with Prime Factorization
| 2 | 719, 538, 703, 807, 990 |
| 3 | 719, 269, 703, 807, 495 |
| 269 | 719, 269, 703, 269, 165 |
| 719, 1, 703, 1, 165 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 269 x 719 x 1 x 703 x 1 x 165 = 134608253670
Therefore, the lowest common multiple of 719,538,703,807,990 is 134608253670.
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.
719 x 538 x 703 x 807 x 990 = 217257721423380
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.
719 : 1, 719
538 : 1, 2, 269, 538
703 : 1, 19, 37, 703
807 : 1, 3, 269, 807
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 719,538,703,807,990, is 1.
Now, the common factors can be found like this.
719:719
538:2x 269
703:19x 37
807:3x 269
990:2x 3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 269 = 1614
Therefore, the value for common factors is 1614.
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 = 217257721423380/(1x1614)
LCM = 217257721423380/1614
LCM = 134608253670
Thus, we can understand that the LCM of 719,538,703,807,990 is 134608253670.
