Given numbers are 124,156,633,257
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 124,156,633,257 is 262241772.
Find LCM of 124,156,633,257 with Prime Factorization
| 2 | 124, 156, 633, 257 |
| 2 | 62, 78, 633, 257 |
| 3 | 31, 39, 633, 257 |
| 31, 13, 211, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 31 x 13 x 211 x 257 = 262241772
Therefore, the lowest common multiple of 124,156,633,257 is 262241772.
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.
124 x 156 x 633 x 257 = 3146901264
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.
124 : 1, 2, 4, 31, 62, 124
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
633 : 1, 3, 211, 633
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 124,156,633,257, is 1.
Now, the common factors can be found like this.
124:2x 2x 31
156:2x 2x 3x 13
633:3x 211
257:257
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 3 = 12
Therefore, the value for common factors is 12.
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 = 3146901264/(1x12)
LCM = 3146901264/12
LCM = 262241772
Thus, we can understand that the LCM of 124,156,633,257 is 262241772.
