Given numbers are 304,551,987,854
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 304,551,987,854 is 530784912.
Find LCM of 304,551,987,854 with Prime Factorization
| 2 | 304, 551, 987, 854 |
| 7 | 152, 551, 987, 427 |
| 19 | 152, 551, 141, 61 |
| 8, 29, 141, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 8 x 29 x 141 x 61 = 530784912
Therefore, the lowest common multiple of 304,551,987,854 is 530784912.
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.
304 x 551 x 987 x 854 = 141188786592
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.
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
551 : 1, 19, 29, 551
987 : 1, 3, 7, 21, 47, 141, 329, 987
854 : 1, 2, 7, 14, 61, 122, 427, 854
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 304,551,987,854, is 1.
Now, the common factors can be found like this.
304:2x 2x 2x 2x 19
551:19x 29
987:3x 7x 47
854:2x 7x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 19 = 266
Therefore, the value for common factors is 266.
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 = 141188786592/(1x266)
LCM = 141188786592/266
LCM = 530784912
Thus, we can understand that the LCM of 304,551,987,854 is 530784912.
