Find LCM of 990,871,323,278,605 with Prime Factorization
| 2 | 990, 871, 323, 278, 605 |
| 5 | 495, 871, 323, 139, 605 |
| 11 | 99, 871, 323, 139, 121 |
| 9, 871, 323, 139, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 9 x 871 x 323 x 139 x 11 = 425856575430
Therefore, the lowest common multiple of 990,871,323,278,605 is 425856575430.
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 871 x 323 x 278 x 605 = 46844223297300
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
871 : 1, 13, 67, 871
323 : 1, 17, 19, 323
278 : 1, 2, 139, 278
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,871,323,278,605, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
871:13x 67
323:17x 19
278:2x 139
605:5x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 46844223297300/(1x110)
LCM = 46844223297300/110
LCM = 425856575430
Thus, we can understand that the LCM of 990,871,323,278,605 is 425856575430.
