Given numbers are 991,198,430,289,737
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,198,430,289,737 is 816864363810.
Find LCM of 991,198,430,289,737 with Prime Factorization
2 | 991, 198, 430, 289, 737 |
11 | 991, 99, 215, 289, 737 |
991, 9, 215, 289, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 991 x 9 x 215 x 289 x 67 = 816864363810
Therefore, the lowest common multiple of 991,198,430,289,737 is 816864363810.
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 198 x 430 x 289 x 737 = 17971016003820
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
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
430 : 1, 2, 5, 10, 43, 86, 215, 430
289 : 1, 17, 289
737 : 1, 11, 67, 737
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,198,430,289,737, is 1.
Now, the common factors can be found like this.
991:991
198:2x 3x 3x 11
430:2x 5x 43
289:17x 17
737:11x 67
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 = 17971016003820/(1x22)
LCM = 17971016003820/22
LCM = 816864363810
Thus, we can understand that the LCM of 991,198,430,289,737 is 816864363810.
