Find LCM of 720,636,547,217,854 with Prime Factorization
2 | 720, 636, 547, 217, 854 |
2 | 360, 318, 547, 217, 427 |
3 | 180, 159, 547, 217, 427 |
7 | 60, 53, 547, 217, 427 |
60, 53, 547, 31, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 60 x 53 x 547 x 31 x 61 = 276302784240
Therefore, the lowest common multiple of 720,636,547,217,854 is 276302784240.
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.
720 x 636 x 547 x 217 x 854 = 46418867752320
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
547 : 1, 547
217 : 1, 7, 31, 217
854 : 1, 2, 7, 14, 61, 122, 427, 854
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,636,547,217,854, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
636:2x 2x 3x 53
547:547
217:7x 31
854:2x 7x 61
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 46418867752320/(1x168)
LCM = 46418867752320/168
LCM = 276302784240
Thus, we can understand that the LCM of 720,636,547,217,854 is 276302784240.
