Given numbers are 754,642,988,257,777
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 754,642,988,257,777 is 612199347396.
Find LCM of 754,642,988,257,777 with Prime Factorization
| 2 | 754, 642, 988, 257, 777 |
| 3 | 377, 321, 494, 257, 777 |
| 13 | 377, 107, 494, 257, 259 |
| 29, 107, 38, 257, 259 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 29 x 107 x 38 x 257 x 259 = 612199347396
Therefore, the lowest common multiple of 754,642,988,257,777 is 612199347396.
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.
754 x 642 x 988 x 257 x 777 = 95503098193776
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.
754 : 1, 2, 13, 26, 29, 58, 377, 754
642 : 1, 2, 3, 6, 107, 214, 321, 642
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
257 : 1, 257
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,642,988,257,777, is 1.
Now, the common factors can be found like this.
754:2x 13x 29
642:2x 3x 107
988:2x 2x 13x 19
257:257
777:3x 7x 37
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 95503098193776/(1x156)
LCM = 95503098193776/156
LCM = 612199347396
Thus, we can understand that the LCM of 754,642,988,257,777 is 612199347396.
