Given numbers are 931,531,993,779,516
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 931,531,993,779,516 is 1153943378532.
Find LCM of 931,531,993,779,516 with Prime Factorization
| 3 | 931, 531, 993, 779, 516 |
| 19 | 931, 177, 331, 779, 172 |
| 49, 177, 331, 41, 172 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 49 x 177 x 331 x 41 x 172 = 1153943378532
Therefore, the lowest common multiple of 931,531,993,779,516 is 1153943378532.
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.
931 x 531 x 993 x 779 x 516 = 197324317728972
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.
931 : 1, 7, 19, 49, 133, 931
531 : 1, 3, 9, 59, 177, 531
993 : 1, 3, 331, 993
779 : 1, 19, 41, 779
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,531,993,779,516, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
531:3x 3x 59
993:3x 331
779:19x 41
516:2x 2x 3x 43
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 19 = 171
Therefore, the value for common factors is 171.
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 = 197324317728972/(1x171)
LCM = 197324317728972/171
LCM = 1153943378532
Thus, we can understand that the LCM of 931,531,993,779,516 is 1153943378532.
