Given numbers are 257,447,562,249,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,447,562,249,338 is 905611145946.
Find LCM of 257,447,562,249,338 with Prime Factorization
| 2 | 257, 447, 562, 249, 338 |
| 3 | 257, 447, 281, 249, 169 |
| 257, 149, 281, 83, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 257 x 149 x 281 x 83 x 169 = 905611145946
Therefore, the lowest common multiple of 257,447,562,249,338 is 905611145946.
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 447 x 562 x 249 x 338 = 5433666875676
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
447 : 1, 3, 149, 447
562 : 1, 2, 281, 562
249 : 1, 3, 83, 249
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,447,562,249,338, is 1.
Now, the common factors can be found like this.
257:257
447:3x 149
562:2x 281
249:3x 83
338:2x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 5433666875676/(1x6)
LCM = 5433666875676/6
LCM = 905611145946
Thus, we can understand that the LCM of 257,447,562,249,338 is 905611145946.
