Given numbers are 889,924,987,257,778
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 889,924,987,257,778 is 551386685388.
Find LCM of 889,924,987,257,778 with Prime Factorization
| 2 | 889, 924, 987, 257, 778 |
| 3 | 889, 462, 987, 257, 389 |
| 7 | 889, 154, 329, 257, 389 |
| 127, 22, 47, 257, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 127 x 22 x 47 x 257 x 389 = 551386685388
Therefore, the lowest common multiple of 889,924,987,257,778 is 551386685388.
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.
889 x 924 x 987 x 257 x 778 = 162107685504072
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.
889 : 1, 7, 127, 889
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
987 : 1, 3, 7, 21, 47, 141, 329, 987
257 : 1, 257
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 889,924,987,257,778, is 1.
Now, the common factors can be found like this.
889:7x 127
924:2x 2x 3x 7x 11
987:3x 7x 47
257:257
778:2x 389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 7 = 294
Therefore, the value for common factors is 294.
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 = 162107685504072/(1x294)
LCM = 162107685504072/294
LCM = 551386685388
Thus, we can understand that the LCM of 889,924,987,257,778 is 551386685388.
