Given numbers are 819,649,985,537,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 819,649,985,537,278 is 26053294937670.
Find LCM of 819,649,985,537,278 with Prime Factorization
| 3 | 819, 649, 985, 537, 278 |
| 273, 649, 985, 179, 278 |
Multiply the prime numbers at the bottom and the left side.
3 x 273 x 649 x 985 x 179 x 278 = 26053294937670
Therefore, the lowest common multiple of 819,649,985,537,278 is 26053294937670.
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.
819 x 649 x 985 x 537 x 278 = 78159884813010
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
649 : 1, 11, 59, 649
985 : 1, 5, 197, 985
537 : 1, 3, 179, 537
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,649,985,537,278, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
649:11x 59
985:5x 197
537:3x 179
278:2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 78159884813010/(1x3)
LCM = 78159884813010/3
LCM = 26053294937670
Thus, we can understand that the LCM of 819,649,985,537,278 is 26053294937670.
