Given numbers are 257,228,570,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,228,570,242 is 35450580.
Find LCM of 257,228,570,242 with Prime Factorization
| 2 | 257, 228, 570, 242 |
| 3 | 257, 114, 285, 121 |
| 19 | 257, 38, 95, 121 |
| 257, 2, 5, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 257 x 2 x 5 x 121 = 35450580
Therefore, the lowest common multiple of 257,228,570,242 is 35450580.
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 228 x 570 x 242 = 8082732240
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
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,228,570,242, is 1.
Now, the common factors can be found like this.
257:257
228:2x 2x 3x 19
570:2x 3x 5x 19
242:2x 11x 11
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 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 8082732240/(1x228)
LCM = 8082732240/228
LCM = 35450580
Thus, we can understand that the LCM of 257,228,570,242 is 35450580.
