Given numbers are 436,338,531,156
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 436,338,531,156 is 39126204.
Find LCM of 436,338,531,156 with Prime Factorization
| 2 | 436, 338, 531, 156 |
| 2 | 218, 169, 531, 78 |
| 3 | 109, 169, 531, 39 |
| 13 | 109, 169, 177, 13 |
| 109, 1, 177, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 109 x 1 x 177 x 13 = 39126204
Therefore, the lowest common multiple of 436,338,531,156 is 39126204.
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.
436 x 338 x 531 x 156 = 12207375648
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.
436 : 1, 2, 4, 109, 218, 436
338 : 1, 2, 13, 26, 169, 338
531 : 1, 3, 9, 59, 177, 531
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,338,531,156, is 1.
Now, the common factors can be found like this.
436:2x 2x 109
338:2x 13x 13
531:3x 3x 59
156:2x 2x 3x 13
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 3x 13 = 312
Therefore, the value for common factors is 312.
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 = 12207375648/(1x312)
LCM = 12207375648/312
LCM = 39126204
Thus, we can understand that the LCM of 436,338,531,156 is 39126204.
