Given numbers are 638,116,917,148,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,116,917,148,779 is 33725561716.
Find LCM of 638,116,917,148,779 with Prime Factorization
2 | 638, 116, 917, 148, 779 |
2 | 319, 58, 917, 74, 779 |
29 | 319, 29, 917, 37, 779 |
11, 1, 917, 37, 779 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 29 x 11 x 1 x 917 x 37 x 779 = 33725561716
Therefore, the lowest common multiple of 638,116,917,148,779 is 33725561716.
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.
638 x 116 x 917 x 148 x 779 = 7824330318112
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
116 : 1, 2, 4, 29, 58, 116
917 : 1, 7, 131, 917
148 : 1, 2, 4, 37, 74, 148
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,116,917,148,779, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
116:2x 2x 29
917:7x 131
148:2x 2x 37
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 2x 2x 29 = 232
Therefore, the value for common factors is 232.
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 = 7824330318112/(1x232)
LCM = 7824330318112/232
LCM = 33725561716
Thus, we can understand that the LCM of 638,116,917,148,779 is 33725561716.
