Given numbers are 542,256,908,458
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 542,256,908,458 is 3606372608.
Find LCM of 542,256,908,458 with Prime Factorization
| 2 | 542, 256, 908, 458 |
| 2 | 271, 128, 454, 229 |
| 271, 64, 227, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 271 x 64 x 227 x 229 = 3606372608
Therefore, the lowest common multiple of 542,256,908,458 is 3606372608.
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.
542 x 256 x 908 x 458 = 57701961728
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.
542 : 1, 2, 271, 542
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
908 : 1, 2, 4, 227, 454, 908
458 : 1, 2, 229, 458
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,256,908,458, is 2.
Now, the common factors can be found like this.
542:2x 271
256:2x 2x 2x 2x 2x 2x 2x 2
908:2x 2x 227
458:2x 229
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 2 = 8
Therefore, the value for common factors is 8.
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 = 57701961728/(2x8)
LCM = 57701961728/16
LCM = 3606372608
Thus, we can understand that the LCM of 542,256,908,458 is 3606372608.
