Given numbers are 257,497,426,426
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,497,426,426 is 766374.
Find LCM of 257,497,426,426 with Prime Factorization
| 2 | 257, 497, 426, 426 |
| 3 | 257, 497, 213, 213 |
| 71 | 257, 497, 71, 71 |
| 257, 7, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 71 x 257 x 7 x 1 x 1 = 766374
Therefore, the lowest common multiple of 257,497,426,426 is 766374.
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 497 x 426 x 426 = 23179748004
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
497 : 1, 7, 71, 497
426 : 1, 2, 3, 6, 71, 142, 213, 426
426 : 1, 2, 3, 6, 71, 142, 213, 426
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,497,426,426, is 1.
Now, the common factors can be found like this.
257:257
497:7x 71
426:2x 3x 71
426:2x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 71x 71 = 30246
Therefore, the value for common factors is 30246.
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 = 23179748004/(1x30246)
LCM = 23179748004/30246
LCM = 766374
Thus, we can understand that the LCM of 257,497,426,426 is 766374.
