Given numbers are 561,942,166,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,942,166,638 is 424002678.
Find LCM of 561,942,166,638 with Prime Factorization
2 | 561, 942, 166, 638 |
3 | 561, 471, 83, 319 |
11 | 187, 157, 83, 319 |
17, 157, 83, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 157 x 83 x 29 = 424002678
Therefore, the lowest common multiple of 561,942,166,638 is 424002678.
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.
561 x 942 x 166 x 638 = 55968353496
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
942 : 1, 2, 3, 6, 157, 314, 471, 942
166 : 1, 2, 83, 166
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,942,166,638, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
942:2x 3x 157
166:2x 83
638:2x 11x 29
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 = 55968353496/(1x132)
LCM = 55968353496/132
LCM = 424002678
Thus, we can understand that the LCM of 561,942,166,638 is 424002678.
