Given numbers are 946,693,389,724,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 946,693,389,724,138 is 193026836772.
Find LCM of 946,693,389,724,138 with Prime Factorization
| 2 | 946, 693, 389, 724, 138 |
| 3 | 473, 693, 389, 362, 69 |
| 11 | 473, 231, 389, 362, 23 |
| 43, 21, 389, 362, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 43 x 21 x 389 x 362 x 23 = 193026836772
Therefore, the lowest common multiple of 946,693,389,724,138 is 193026836772.
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.
946 x 693 x 389 x 724 x 138 = 25479542453904
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.
946 : 1, 2, 11, 22, 43, 86, 473, 946
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
389 : 1, 389
724 : 1, 2, 4, 181, 362, 724
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,693,389,724,138, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
693:3x 3x 7x 11
389:389
724:2x 2x 181
138:2x 3x 23
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 11 = 132
Therefore, the value for common factors is 132.
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 = 25479542453904/(1x132)
LCM = 25479542453904/132
LCM = 193026836772
Thus, we can understand that the LCM of 946,693,389,724,138 is 193026836772.
