Given numbers are 722,988,923,89
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,988,923,89 is 118620268.
Find LCM of 722,988,923,89 with Prime Factorization
| 2 | 722, 988, 923, 89 |
| 13 | 361, 494, 923, 89 |
| 19 | 361, 38, 71, 89 |
| 19, 2, 71, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 19 x 2 x 71 x 89 = 118620268
Therefore, the lowest common multiple of 722,988,923,89 is 118620268.
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.
722 x 988 x 923 x 89 = 58598412392
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.
722 : 1, 2, 19, 38, 361, 722
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
923 : 1, 13, 71, 923
89 : 1, 89
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,988,923,89, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
988:2x 2x 13x 19
923:13x 71
89:89
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 = 58598412392/(1x494)
LCM = 58598412392/494
LCM = 118620268
Thus, we can understand that the LCM of 722,988,923,89 is 118620268.
