Given numbers are 542,345,788,296
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 542,345,788,296 is 5451880440.
Find LCM of 542,345,788,296 with Prime Factorization
| 2 | 542, 345, 788, 296 |
| 2 | 271, 345, 394, 148 |
| 271, 345, 197, 74 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 271 x 345 x 197 x 74 = 5451880440
Therefore, the lowest common multiple of 542,345,788,296 is 5451880440.
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 345 x 788 x 296 = 43615043520
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
345 : 1, 3, 5, 15, 23, 69, 115, 345
788 : 1, 2, 4, 197, 394, 788
296 : 1, 2, 4, 8, 37, 74, 148, 296
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,345,788,296, is 1.
Now, the common factors can be found like this.
542:2x 271
345:3x 5x 23
788:2x 2x 197
296:2x 2x 2x 37
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 = 43615043520/(1x8)
LCM = 43615043520/8
LCM = 5451880440
Thus, we can understand that the LCM of 542,345,788,296 is 5451880440.
