Given numbers are 853,538,243,462,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 853,538,243,462,742 is 455097212262.
Find LCM of 853,538,243,462,742 with Prime Factorization
| 2 | 853, 538, 243, 462, 742 |
| 3 | 853, 269, 243, 231, 371 |
| 7 | 853, 269, 81, 77, 371 |
| 853, 269, 81, 11, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 853 x 269 x 81 x 11 x 53 = 455097212262
Therefore, the lowest common multiple of 853,538,243,462,742 is 455097212262.
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.
853 x 538 x 243 x 462 x 742 = 38228165830008
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.
853 : 1, 853
538 : 1, 2, 269, 538
243 : 1, 3, 9, 27, 81, 243
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,538,243,462,742, is 1.
Now, the common factors can be found like this.
853:853
538:2x 269
243:3x 3x 3x 3x 3
462:2x 3x 7x 11
742:2x 7x 53
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 7 = 84
Therefore, the value for common factors is 84.
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 = 38228165830008/(1x84)
LCM = 38228165830008/84
LCM = 455097212262
Thus, we can understand that the LCM of 853,538,243,462,742 is 455097212262.
