Given numbers are 257,819,231,483,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,819,231,483,756 is 639026388.
Find LCM of 257,819,231,483,756 with Prime Factorization
| 3 | 257, 819, 231, 483, 756 |
| 3 | 257, 273, 77, 161, 252 |
| 7 | 257, 91, 77, 161, 84 |
| 257, 13, 11, 23, 12 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 257 x 13 x 11 x 23 x 12 = 639026388
Therefore, the lowest common multiple of 257,819,231,483,756 is 639026388.
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.
257 x 819 x 231 x 483 x 756 = 17754070137804
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.
257 : 1, 257
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
231 : 1, 3, 7, 11, 21, 33, 77, 231
483 : 1, 3, 7, 21, 23, 69, 161, 483
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,819,231,483,756, is 1.
Now, the common factors can be found like this.
257:257
819:3x 3x 7x 13
231:3x 7x 11
483:3x 7x 23
756:2x 2x 3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 7x 7x 7 = 27783
Therefore, the value for common factors is 27783.
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 = 17754070137804/(1x27783)
LCM = 17754070137804/27783
LCM = 639026388
Thus, we can understand that the LCM of 257,819,231,483,756 is 639026388.
