Given numbers are 169,398,494,760
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,398,494,760 is 25559560.
Find LCM of 169,398,494,760 with Prime Factorization
| 2 | 169, 398, 494, 760 |
| 13 | 169, 199, 247, 380 |
| 19 | 13, 199, 19, 380 |
| 13, 199, 1, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 13 x 199 x 1 x 20 = 25559560
Therefore, the lowest common multiple of 169,398,494,760 is 25559560.
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.
169 x 398 x 494 x 760 = 25252845280
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.
169 : 1, 13, 169
398 : 1, 2, 199, 398
494 : 1, 2, 13, 19, 26, 38, 247, 494
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,398,494,760, is 1.
Now, the common factors can be found like this.
169:13x 13
398:2x 199
494:2x 13x 19
760:2x 2x 2x 5x 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 2x 13x 19 = 988
Therefore, the value for common factors is 988.
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 = 25252845280/(1x988)
LCM = 25252845280/988
LCM = 25559560
Thus, we can understand that the LCM of 169,398,494,760 is 25559560.
