Given numbers are 154,869,553,531
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,869,553,531 is 6460146.
Find LCM of 154,869,553,531 with Prime Factorization
| 7 | 154, 869, 553, 531 |
| 11 | 22, 869, 79, 531 |
| 79 | 2, 79, 79, 531 |
| 2, 1, 1, 531 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 79 x 2 x 1 x 1 x 531 = 6460146
Therefore, the lowest common multiple of 154,869,553,531 is 6460146.
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.
154 x 869 x 553 x 531 = 39297068118
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
869 : 1, 11, 79, 869
553 : 1, 7, 79, 553
531 : 1, 3, 9, 59, 177, 531
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,869,553,531, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
869:11x 79
553:7x 79
531:3x 3x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 79 = 6083
Therefore, the value for common factors is 6083.
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 = 39297068118/(1x6083)
LCM = 39297068118/6083
LCM = 6460146
Thus, we can understand that the LCM of 154,869,553,531 is 6460146.
