Find LCM of 543,432,936,338,120 with Prime Factorization
| 2 | 543, 432, 936, 338, 120 |
| 2 | 543, 216, 468, 169, 60 |
| 2 | 543, 108, 234, 169, 30 |
| 3 | 543, 54, 117, 169, 15 |
| 3 | 181, 18, 39, 169, 5 |
| 13 | 181, 6, 13, 169, 5 |
| 181, 6, 1, 13, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 13 x 181 x 6 x 1 x 13 x 5 = 66072240
Therefore, the lowest common multiple of 543,432,936,338,120 is 66072240.
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.
543 x 432 x 936 x 338 x 120 = 8905480796160
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.
543 : 1, 3, 181, 543
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
338 : 1, 2, 13, 26, 169, 338
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,432,936,338,120, is 1.
Now, the common factors can be found like this.
543:3x 181
432:2x 2x 2x 2x 3x 3x 3
936:2x 2x 2x 3x 3x 13
338:2x 13x 13
120:2x 2x 2x 3x 5
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 2x 2x 2x 3x 3x 3x 3x 13 = 134784
Therefore, the value for common factors is 134784.
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 = 8905480796160/(1x134784)
LCM = 8905480796160/134784
LCM = 66072240
Thus, we can understand that the LCM of 543,432,936,338,120 is 66072240.
