Given numbers are 991,757,667,644,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,757,667,644,745 is 10437816846940.
Find LCM of 991,757,667,644,745 with Prime Factorization
23 | 991, 757, 667, 644, 745 |
991, 757, 29, 28, 745 |
Multiply the prime numbers at the bottom and the left side.
23 x 991 x 757 x 29 x 28 x 745 = 10437816846940
Therefore, the lowest common multiple of 991,757,667,644,745 is 10437816846940.
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 757 x 667 x 644 x 745 = 240069787479620
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
757 : 1, 757
667 : 1, 23, 29, 667
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,757,667,644,745, is 1.
Now, the common factors can be found like this.
991:991
757:757
667:23x 29
644:2x 2x 7x 23
745:5x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 240069787479620/(1x23)
LCM = 240069787479620/23
LCM = 10437816846940
Thus, we can understand that the LCM of 991,757,667,644,745 is 10437816846940.
