Given numbers are 991,403,534,682
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,403,534,682 is 2345917002.
Find LCM of 991,403,534,682 with Prime Factorization
| 2 | 991, 403, 534, 682 |
| 31 | 991, 403, 267, 341 |
| 991, 13, 267, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 991 x 13 x 267 x 11 = 2345917002
Therefore, the lowest common multiple of 991,403,534,682 is 2345917002.
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.
991 x 403 x 534 x 682 = 145446854124
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.
991 : 1, 991
403 : 1, 13, 31, 403
534 : 1, 2, 3, 6, 89, 178, 267, 534
682 : 1, 2, 11, 22, 31, 62, 341, 682
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,403,534,682, is 1.
Now, the common factors can be found like this.
991:991
403:13x 31
534:2x 3x 89
682:2x 11x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 31 = 62
Therefore, the value for common factors is 62.
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 = 145446854124/(1x62)
LCM = 145446854124/62
LCM = 2345917002
Thus, we can understand that the LCM of 991,403,534,682 is 2345917002.
