Find LCM of 343,403,756,987,117 with Prime Factorization
| 3 | 343, 403, 756, 987, 117 |
| 3 | 343, 403, 252, 329, 39 |
| 7 | 343, 403, 84, 329, 13 |
| 13 | 49, 403, 12, 47, 13 |
| 49, 31, 12, 47, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 13 x 49 x 31 x 12 x 47 x 1 = 701650404
Therefore, the lowest common multiple of 343,403,756,987,117 is 701650404.
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.
343 x 403 x 756 x 987 x 117 = 12067685298396
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.
343 : 1, 7, 49, 343
403 : 1, 13, 31, 403
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
987 : 1, 3, 7, 21, 47, 141, 329, 987
117 : 1, 3, 9, 13, 39, 117
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,403,756,987,117, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
403:13x 31
756:2x 2x 3x 3x 3x 7
987:3x 7x 47
117:3x 3x 13
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 7x 7x 13 = 17199
Therefore, the value for common factors is 17199.
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 = 12067685298396/(1x17199)
LCM = 12067685298396/17199
LCM = 701650404
Thus, we can understand that the LCM of 343,403,756,987,117 is 701650404.
