Given numbers are 810,767,338,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 810,767,338,505 is 815727510.
Find LCM of 810,767,338,505 with Prime Factorization
| 2 | 810, 767, 338, 505 |
| 5 | 405, 767, 169, 505 |
| 13 | 81, 767, 169, 101 |
| 81, 59, 13, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 81 x 59 x 13 x 101 = 815727510
Therefore, the lowest common multiple of 810,767,338,505 is 815727510.
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.
810 x 767 x 338 x 505 = 106044576300
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
767 : 1, 13, 59, 767
338 : 1, 2, 13, 26, 169, 338
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,767,338,505, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
767:13x 59
338:2x 13x 13
505:5x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 106044576300/(1x130)
LCM = 106044576300/130
LCM = 815727510
Thus, we can understand that the LCM of 810,767,338,505 is 815727510.
