Given numbers are 851,540,792,143
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,540,792,143 is 131428440.
Find LCM of 851,540,792,143 with Prime Factorization
| 2 | 851, 540, 792, 143 |
| 2 | 851, 270, 396, 143 |
| 3 | 851, 135, 198, 143 |
| 3 | 851, 45, 66, 143 |
| 11 | 851, 15, 22, 143 |
| 851, 15, 2, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 851 x 15 x 2 x 13 = 131428440
Therefore, the lowest common multiple of 851,540,792,143 is 131428440.
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.
851 x 540 x 792 x 143 = 52045662240
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.
851 : 1, 23, 37, 851
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
143 : 1, 11, 13, 143
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,540,792,143, is 1.
Now, the common factors can be found like this.
851:23x 37
540:2x 2x 3x 3x 3x 5
792:2x 2x 2x 3x 3x 11
143:11x 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 3x 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 52045662240/(1x396)
LCM = 52045662240/396
LCM = 131428440
Thus, we can understand that the LCM of 851,540,792,143 is 131428440.
