Given numbers are 123,593,689,722,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,593,689,722,988 is 72568178124.
Find LCM of 123,593,689,722,988 with Prime Factorization
| 2 | 123, 593, 689, 722, 988 |
| 13 | 123, 593, 689, 361, 494 |
| 19 | 123, 593, 53, 361, 38 |
| 123, 593, 53, 19, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 123 x 593 x 53 x 19 x 2 = 72568178124
Therefore, the lowest common multiple of 123,593,689,722,988 is 72568178124.
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.
123 x 593 x 689 x 722 x 988 = 35848679993256
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.
123 : 1, 3, 41, 123
593 : 1, 593
689 : 1, 13, 53, 689
722 : 1, 2, 19, 38, 361, 722
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,593,689,722,988, is 1.
Now, the common factors can be found like this.
123:3x 41
593:593
689:13x 53
722:2x 19x 19
988:2x 2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 19 = 494
Therefore, the value for common factors is 494.
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 = 35848679993256/(1x494)
LCM = 35848679993256/494
LCM = 72568178124
Thus, we can understand that the LCM of 123,593,689,722,988 is 72568178124.
