Given numbers are 689,931,789,327,169
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,931,789,327,169 is 717159500967.
Find LCM of 689,931,789,327,169 with Prime Factorization
| 3 | 689, 931, 789, 327, 169 |
| 13 | 689, 931, 263, 109, 169 |
| 53, 931, 263, 109, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 53 x 931 x 263 x 109 x 13 = 717159500967
Therefore, the lowest common multiple of 689,931,789,327,169 is 717159500967.
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.
689 x 931 x 789 x 327 x 169 = 27969220537713
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.
689 : 1, 13, 53, 689
931 : 1, 7, 19, 49, 133, 931
789 : 1, 3, 263, 789
327 : 1, 3, 109, 327
169 : 1, 13, 169
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,931,789,327,169, is 1.
Now, the common factors can be found like this.
689:13x 53
931:7x 7x 19
789:3x 263
327:3x 109
169:13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 27969220537713/(1x39)
LCM = 27969220537713/39
LCM = 717159500967
Thus, we can understand that the LCM of 689,931,789,327,169 is 717159500967.
