Given numbers are 257,637,277,252,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,637,277,252,405 is 73462776660.
Find LCM of 257,637,277,252,405 with Prime Factorization
| 3 | 257, 637, 277, 252, 405 |
| 3 | 257, 637, 277, 84, 135 |
| 7 | 257, 637, 277, 28, 45 |
| 257, 91, 277, 4, 45 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 257 x 91 x 277 x 4 x 45 = 73462776660
Therefore, the lowest common multiple of 257,637,277,252,405 is 73462776660.
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.
257 x 637 x 277 x 252 x 405 = 4628154929580
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.
257 : 1, 257
637 : 1, 7, 13, 49, 91, 637
277 : 1, 277
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,637,277,252,405, is 1.
Now, the common factors can be found like this.
257:257
637:7x 7x 13
277:277
252:2x 2x 3x 3x 7
405:3x 3x 3x 3x 5
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 7 = 63
Therefore, the value for common factors is 63.
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 = 4628154929580/(1x63)
LCM = 4628154929580/63
LCM = 73462776660
Thus, we can understand that the LCM of 257,637,277,252,405 is 73462776660.
