Given numbers are 780,589,538,853,268
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,589,538,853,268 is 7062948040980.
Find LCM of 780,589,538,853,268 with Prime Factorization
| 2 | 780, 589, 538, 853, 268 |
| 2 | 390, 589, 269, 853, 134 |
| 195, 589, 269, 853, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 195 x 589 x 269 x 853 x 67 = 7062948040980
Therefore, the lowest common multiple of 780,589,538,853,268 is 7062948040980.
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.
780 x 589 x 538 x 853 x 268 = 56503584327840
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.
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
589 : 1, 19, 31, 589
538 : 1, 2, 269, 538
853 : 1, 853
268 : 1, 2, 4, 67, 134, 268
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,589,538,853,268, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
589:19x 31
538:2x 269
853:853
268:2x 2x 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 2x 2 = 8
Therefore, the value for common factors is 8.
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 = 56503584327840/(1x8)
LCM = 56503584327840/8
LCM = 7062948040980
Thus, we can understand that the LCM of 780,589,538,853,268 is 7062948040980.
