The LCM of 320,497,404,245,659 is 74098803520.
Find LCM of 320,497,404,245,659 with Prime Factorization
| 2 | 320, 497, 404, 245, 659 |
| 2 | 160, 497, 202, 245, 659 |
| 5 | 80, 497, 101, 245, 659 |
| 7 | 16, 497, 101, 49, 659 |
| 16, 71, 101, 7, 659 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 16 x 71 x 101 x 7 x 659 = 74098803520
Therefore, the lowest common multiple of 320,497,404,245,659 is 74098803520.
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.
320 x 497 x 404 x 245 x 659 = 10373832492800
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.
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
497 : 1, 7, 71, 497
404 : 1, 2, 4, 101, 202, 404
245 : 1, 5, 7, 35, 49, 245
659 : 1, 659
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,497,404,245,659, is 1.
Now, the common factors can be found like this.
320:2x 2x 2x 2x 2x 2x 5
497:7x 71
404:2x 2x 101
245:5x 7x 7
659:659
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 10373832492800/(1x140)
LCM = 10373832492800/140
LCM = 74098803520
Thus, we can understand that the LCM of 320,497,404,245,659 is 74098803520.
