Given numbers are 278,871,627,242,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,871,627,242,689 is 88511366658.
Find LCM of 278,871,627,242,689 with Prime Factorization
2 | 278, 871, 627, 242, 689 |
11 | 139, 871, 627, 121, 689 |
13 | 139, 871, 57, 11, 689 |
139, 67, 57, 11, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 139 x 67 x 57 x 11 x 53 = 88511366658
Therefore, the lowest common multiple of 278,871,627,242,689 is 88511366658.
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.
278 x 871 x 627 x 242 x 689 = 25314250864188
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.
278 : 1, 2, 139, 278
871 : 1, 13, 67, 871
627 : 1, 3, 11, 19, 33, 57, 209, 627
242 : 1, 2, 11, 22, 121, 242
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,871,627,242,689, is 1.
Now, the common factors can be found like this.
278:2x 139
871:13x 67
627:3x 11x 19
242:2x 11x 11
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 13 = 286
Therefore, the value for common factors is 286.
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 = 25314250864188/(1x286)
LCM = 25314250864188/286
LCM = 88511366658
Thus, we can understand that the LCM of 278,871,627,242,689 is 88511366658.
