Given numbers are 991,351,374,616
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,351,374,616 is 3642590952.
Find LCM of 991,351,374,616 with Prime Factorization
| 2 | 991, 351, 374, 616 |
| 11 | 991, 351, 187, 308 |
| 991, 351, 17, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 991 x 351 x 17 x 28 = 3642590952
Therefore, the lowest common multiple of 991,351,374,616 is 3642590952.
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 351 x 374 x 616 = 80137000944
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
351 : 1, 3, 9, 13, 27, 39, 117, 351
374 : 1, 2, 11, 17, 22, 34, 187, 374
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,351,374,616, is 1.
Now, the common factors can be found like this.
991:991
351:3x 3x 3x 13
374:2x 11x 17
616:2x 2x 2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 80137000944/(1x22)
LCM = 80137000944/22
LCM = 3642590952
Thus, we can understand that the LCM of 991,351,374,616 is 3642590952.
