Given numbers are 169,595,978,921,900
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,595,978,921,900 is 905737095900.
Find LCM of 169,595,978,921,900 with Prime Factorization
| 2 | 169, 595, 978, 921, 900 |
| 3 | 169, 595, 489, 921, 450 |
| 5 | 169, 595, 163, 307, 150 |
| 169, 119, 163, 307, 30 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 169 x 119 x 163 x 307 x 30 = 905737095900
Therefore, the lowest common multiple of 169,595,978,921,900 is 905737095900.
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 595 x 978 x 921 x 900 = 81516338631000
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
595 : 1, 5, 7, 17, 35, 85, 119, 595
978 : 1, 2, 3, 6, 163, 326, 489, 978
921 : 1, 3, 307, 921
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,595,978,921,900, is 1.
Now, the common factors can be found like this.
169:13x 13
595:5x 7x 17
978:2x 3x 163
921:3x 307
900:2x 2x 3x 3x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 81516338631000/(1x90)
LCM = 81516338631000/90
LCM = 905737095900
Thus, we can understand that the LCM of 169,595,978,921,900 is 905737095900.
