Find LCM of 328,640,131,519,395 with Prime Factorization
2 | 328, 640, 131, 519, 395 |
2 | 164, 320, 131, 519, 395 |
2 | 82, 160, 131, 519, 395 |
5 | 41, 80, 131, 519, 395 |
41, 16, 131, 519, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 41 x 16 x 131 x 519 x 79 = 140938477440
Therefore, the lowest common multiple of 328,640,131,519,395 is 140938477440.
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.
328 x 640 x 131 x 519 x 395 = 5637539097600
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.
328 : 1, 2, 4, 8, 41, 82, 164, 328
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
131 : 1, 131
519 : 1, 3, 173, 519
395 : 1, 5, 79, 395
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,640,131,519,395, is 1.
Now, the common factors can be found like this.
328:2x 2x 2x 41
640:2x 2x 2x 2x 2x 2x 2x 5
131:131
519:3x 173
395:5x 79
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 = 5637539097600/(1x40)
LCM = 5637539097600/40
LCM = 140938477440
Thus, we can understand that the LCM of 328,640,131,519,395 is 140938477440.
