Given numbers are 768,754,889,770,654
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,754,889,770,654 is 1543098036480.
Find LCM of 768,754,889,770,654 with Prime Factorization
| 2 | 768, 754, 889, 770, 654 |
| 3 | 384, 377, 889, 385, 327 |
| 7 | 128, 377, 889, 385, 109 |
| 128, 377, 127, 55, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 128 x 377 x 127 x 55 x 109 = 1543098036480
Therefore, the lowest common multiple of 768,754,889,770,654 is 1543098036480.
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.
768 x 754 x 889 x 770 x 654 = 259240470128640
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
754 : 1, 2, 13, 26, 29, 58, 377, 754
889 : 1, 7, 127, 889
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
654 : 1, 2, 3, 6, 109, 218, 327, 654
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,754,889,770,654, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
754:2x 13x 29
889:7x 127
770:2x 5x 7x 11
654:2x 3x 109
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 2x 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 259240470128640/(1x168)
LCM = 259240470128640/168
LCM = 1543098036480
Thus, we can understand that the LCM of 768,754,889,770,654 is 1543098036480.
