Find LCM of 990,497,369,595,778 with Prime Factorization
| 2 | 990, 497, 369, 595, 778 |
| 3 | 495, 497, 369, 595, 389 |
| 3 | 165, 497, 123, 595, 389 |
| 5 | 55, 497, 41, 595, 389 |
| 7 | 11, 497, 41, 119, 389 |
| 11, 71, 41, 17, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 11 x 71 x 41 x 17 x 389 = 133405569990
Therefore, the lowest common multiple of 990,497,369,595,778 is 133405569990.
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.
990 x 497 x 369 x 595 x 778 = 84045509093700
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.
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
497 : 1, 7, 71, 497
369 : 1, 3, 9, 41, 123, 369
595 : 1, 5, 7, 17, 35, 85, 119, 595
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,497,369,595,778, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
497:7x 71
369:3x 3x 41
595:5x 7x 17
778:2x 389
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 5x 7 = 630
Therefore, the value for common factors is 630.
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 = 84045509093700/(1x630)
LCM = 84045509093700/630
LCM = 133405569990
Thus, we can understand that the LCM of 990,497,369,595,778 is 133405569990.
