Given numbers are 265,238,782,810
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 265,238,782,810 is 117499410.
Find LCM of 265,238,782,810 with Prime Factorization
| 2 | 265, 238, 782, 810 |
| 5 | 265, 119, 391, 405 |
| 17 | 53, 119, 391, 81 |
| 53, 7, 23, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 53 x 7 x 23 x 81 = 117499410
Therefore, the lowest common multiple of 265,238,782,810 is 117499410.
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.
265 x 238 x 782 x 810 = 39949799400
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.
265 : 1, 5, 53, 265
238 : 1, 2, 7, 14, 17, 34, 119, 238
782 : 1, 2, 17, 23, 34, 46, 391, 782
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 265,238,782,810, is 1.
Now, the common factors can be found like this.
265:5x 53
238:2x 7x 17
782:2x 17x 23
810:2x 3x 3x 3x 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 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 39949799400/(1x340)
LCM = 39949799400/340
LCM = 117499410
Thus, we can understand that the LCM of 265,238,782,810 is 117499410.
