Given numbers are 721,897,494,161,737
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,897,494,161,737 is 18112516422.
Find LCM of 721,897,494,161,737 with Prime Factorization
| 7 | 721, 897, 494, 161, 737 |
| 13 | 103, 897, 494, 23, 737 |
| 23 | 103, 69, 38, 23, 737 |
| 103, 3, 38, 1, 737 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 23 x 103 x 3 x 38 x 1 x 737 = 18112516422
Therefore, the lowest common multiple of 721,897,494,161,737 is 18112516422.
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.
721 x 897 x 494 x 161 x 737 = 37909496871246
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.
721 : 1, 7, 103, 721
897 : 1, 3, 13, 23, 39, 69, 299, 897
494 : 1, 2, 13, 19, 26, 38, 247, 494
161 : 1, 7, 23, 161
737 : 1, 11, 67, 737
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,897,494,161,737, is 1.
Now, the common factors can be found like this.
721:7x 103
897:3x 13x 23
494:2x 13x 19
161:7x 23
737:11x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 13x 23 = 2093
Therefore, the value for common factors is 2093.
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 = 37909496871246/(1x2093)
LCM = 37909496871246/2093
LCM = 18112516422
Thus, we can understand that the LCM of 721,897,494,161,737 is 18112516422.
