Given numbers are 527,420,340,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 527,420,340,120 is 442680.
Find LCM of 527,420,340,120 with Prime Factorization
| 2 | 527, 420, 340, 120 |
| 2 | 527, 210, 170, 60 |
| 3 | 527, 105, 85, 30 |
| 5 | 527, 35, 85, 10 |
| 17 | 527, 7, 17, 2 |
| 31, 7, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 31 x 7 x 1 x 2 = 442680
Therefore, the lowest common multiple of 527,420,340,120 is 442680.
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.
527 x 420 x 340 x 120 = 9030672000
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.
527 : 1, 17, 31, 527
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
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 527,420,340,120, is 1.
Now, the common factors can be found like this.
527:17x 31
420:2x 2x 3x 5x 7
340:2x 2x 5x 17
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 3x 5x 5x 17 = 20400
Therefore, the value for common factors is 20400.
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 = 9030672000/(1x20400)
LCM = 9030672000/20400
LCM = 442680
Thus, we can understand that the LCM of 527,420,340,120 is 442680.
