Given numbers are 392,865,130,108,109
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,865,130,108,109 is 12972861720.
Find LCM of 392,865,130,108,109 with Prime Factorization
| 2 | 392, 865, 130, 108, 109 |
| 2 | 196, 865, 65, 54, 109 |
| 5 | 98, 865, 65, 27, 109 |
| 98, 173, 13, 27, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 98 x 173 x 13 x 27 x 109 = 12972861720
Therefore, the lowest common multiple of 392,865,130,108,109 is 12972861720.
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.
392 x 865 x 130 x 108 x 109 = 518914468800
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
865 : 1, 5, 173, 865
130 : 1, 2, 5, 10, 13, 26, 65, 130
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
109 : 1, 109
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,865,130,108,109, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
865:5x 173
130:2x 5x 13
108:2x 2x 3x 3x 3
109:109
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 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 518914468800/(1x40)
LCM = 518914468800/40
LCM = 12972861720
Thus, we can understand that the LCM of 392,865,130,108,109 is 12972861720.
