Find LCM of 165,703,513,993,420 with Prime Factorization
3 | 165, 703, 513, 993, 420 |
5 | 55, 703, 171, 331, 140 |
19 | 11, 703, 171, 331, 28 |
11, 37, 9, 331, 28 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 11 x 37 x 9 x 331 x 28 = 9675374940
Therefore, the lowest common multiple of 165,703,513,993,420 is 9675374940.
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.
165 x 703 x 513 x 993 x 420 = 24817336721100
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
703 : 1, 19, 37, 703
513 : 1, 3, 9, 19, 27, 57, 171, 513
993 : 1, 3, 331, 993
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,703,513,993,420, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
703:19x 37
513:3x 3x 3x 19
993:3x 331
420:2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 19 = 2565
Therefore, the value for common factors is 2565.
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 = 24817336721100/(1x2565)
LCM = 24817336721100/2565
LCM = 9675374940
Thus, we can understand that the LCM of 165,703,513,993,420 is 9675374940.
