Given numbers are 331,340,611,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 331,340,611,442 is 68761940.
Find LCM of 331,340,611,442 with Prime Factorization
| 2 | 331, 340, 611, 442 |
| 13 | 331, 170, 611, 221 |
| 17 | 331, 170, 47, 17 |
| 331, 10, 47, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 331 x 10 x 47 x 1 = 68761940
Therefore, the lowest common multiple of 331,340,611,442 is 68761940.
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.
331 x 340 x 611 x 442 = 30392777480
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.
331 : 1, 331
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
611 : 1, 13, 47, 611
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,340,611,442, is 1.
Now, the common factors can be found like this.
331:331
340:2x 2x 5x 17
611:13x 47
442:2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 17 = 442
Therefore, the value for common factors is 442.
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 = 30392777480/(1x442)
LCM = 30392777480/442
LCM = 68761940
Thus, we can understand that the LCM of 331,340,611,442 is 68761940.
