Given numbers are 852,420,755,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 852,420,755,380 is 85553580.
Find LCM of 852,420,755,380 with Prime Factorization
| 2 | 852, 420, 755, 380 |
| 2 | 426, 210, 755, 190 |
| 3 | 213, 105, 755, 95 |
| 5 | 71, 35, 755, 95 |
| 71, 7, 151, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 71 x 7 x 151 x 19 = 85553580
Therefore, the lowest common multiple of 852,420,755,380 is 85553580.
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.
852 x 420 x 755 x 380 = 102664296000
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.
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
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
755 : 1, 5, 151, 755
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 852,420,755,380, is 1.
Now, the common factors can be found like this.
852:2x 2x 3x 71
420:2x 2x 3x 5x 7
755:5x 151
380:2x 2x 5x 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 3x 5x 5 = 1200
Therefore, the value for common factors is 1200.
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 = 102664296000/(1x1200)
LCM = 102664296000/1200
LCM = 85553580
Thus, we can understand that the LCM of 852,420,755,380 is 85553580.
