Given numbers are 159,691,981,395,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 159,691,981,395,648 is 1021768515720.
Find LCM of 159,691,981,395,648 with Prime Factorization
3 | 159, 691, 981, 395, 648 |
3 | 53, 691, 327, 395, 216 |
53, 691, 109, 395, 72 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 53 x 691 x 109 x 395 x 72 = 1021768515720
Therefore, the lowest common multiple of 159,691,981,395,648 is 1021768515720.
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.
159 x 691 x 981 x 395 x 648 = 27587749924440
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.
159 : 1, 3, 53, 159
691 : 1, 691
981 : 1, 3, 9, 109, 327, 981
395 : 1, 5, 79, 395
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 159,691,981,395,648, is 1.
Now, the common factors can be found like this.
159:3x 53
691:691
981:3x 3x 109
395:5x 79
648:2x 2x 2x 3x 3x 3x 3
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 3 = 27
Therefore, the value for common factors is 27.
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 = 27587749924440/(1x27)
LCM = 27587749924440/27
LCM = 1021768515720
Thus, we can understand that the LCM of 159,691,981,395,648 is 1021768515720.
