Given numbers are 177,658,756,121,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 177,658,756,121,779 is 197603436492.
Find LCM of 177,658,756,121,779 with Prime Factorization
| 2 | 177, 658, 756, 121, 779 |
| 3 | 177, 329, 378, 121, 779 |
| 7 | 59, 329, 126, 121, 779 |
| 59, 47, 18, 121, 779 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 59 x 47 x 18 x 121 x 779 = 197603436492
Therefore, the lowest common multiple of 177,658,756,121,779 is 197603436492.
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.
177 x 658 x 756 x 121 x 779 = 8299344332664
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.
177 : 1, 3, 59, 177
658 : 1, 2, 7, 14, 47, 94, 329, 658
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
121 : 1, 11, 121
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,658,756,121,779, is 1.
Now, the common factors can be found like this.
177:3x 59
658:2x 7x 47
756:2x 2x 3x 3x 3x 7
121:11x 11
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 8299344332664/(1x42)
LCM = 8299344332664/42
LCM = 197603436492
Thus, we can understand that the LCM of 177,658,756,121,779 is 197603436492.
