Given numbers are 424,532,836,38
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 424,532,836,38 is 620312.
Find LCM of 424,532,836,38 with Prime Factorization
| 2 | 424, 532, 836, 38 |
| 2 | 212, 266, 418, 19 |
| 19 | 106, 133, 209, 19 |
| 106, 7, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 106 x 7 x 11 x 1 = 620312
Therefore, the lowest common multiple of 424,532,836,38 is 620312.
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.
424 x 532 x 836 x 38 = 7165844224
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.
424 : 1, 2, 4, 8, 53, 106, 212, 424
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
38 : 1, 2, 19, 38
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,532,836,38, is 2.
Now, the common factors can be found like this.
424:2x 2x 2x 53
532:2x 2x 7x 19
836:2x 2x 11x 19
38:2x 19
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 2x 2x 19x 19 = 5776
Therefore, the value for common factors is 5776.
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 = 7165844224/(2x5776)
LCM = 7165844224/11552
LCM = 620312
Thus, we can understand that the LCM of 424,532,836,38 is 620312.
