Find LCM of 161,605,672,344,340 with Prime Factorization
2 | 161, 605, 672, 344, 340 |
2 | 161, 605, 336, 172, 170 |
2 | 161, 605, 168, 86, 85 |
5 | 161, 605, 84, 43, 85 |
7 | 161, 121, 84, 43, 17 |
23, 121, 12, 43, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 23 x 121 x 12 x 43 x 17 = 6835493280
Therefore, the lowest common multiple of 161,605,672,344,340 is 6835493280.
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.
161 x 605 x 672 x 344 x 340 = 7655752473600
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.
161 : 1, 7, 23, 161
605 : 1, 5, 11, 55, 121, 605
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
344 : 1, 2, 4, 8, 43, 86, 172, 344
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,605,672,344,340, is 1.
Now, the common factors can be found like this.
161:7x 23
605:5x 11x 11
672:2x 2x 2x 2x 2x 3x 7
344:2x 2x 2x 43
340:2x 2x 5x 17
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 2x 2x 5x 7 = 1120
Therefore, the value for common factors is 1120.
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 = 7655752473600/(1x1120)
LCM = 7655752473600/1120
LCM = 6835493280
Thus, we can understand that the LCM of 161,605,672,344,340 is 6835493280.
