Given numbers are 279,329,819,549
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,329,819,549 is 72790263.
Find LCM of 279,329,819,549 with Prime Factorization
| 3 | 279, 329, 819, 549 |
| 3 | 93, 329, 273, 183 |
| 7 | 31, 329, 91, 61 |
| 31, 47, 13, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 31 x 47 x 13 x 61 = 72790263
Therefore, the lowest common multiple of 279,329,819,549 is 72790263.
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.
279 x 329 x 819 x 549 = 41272079121
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.
279 : 1, 3, 9, 31, 93, 279
329 : 1, 7, 47, 329
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
549 : 1, 3, 9, 61, 183, 549
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,329,819,549, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
329:7x 47
819:3x 3x 7x 13
549:3x 3x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 7 = 567
Therefore, the value for common factors is 567.
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 = 41272079121/(1x567)
LCM = 41272079121/567
LCM = 72790263
Thus, we can understand that the LCM of 279,329,819,549 is 72790263.
