Given numbers are 988,522,556,371,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 988,522,556,371,770 is 731389719060.
Find LCM of 988,522,556,371,770 with Prime Factorization
| 2 | 988, 522, 556, 371, 770 |
| 2 | 494, 261, 278, 371, 385 |
| 7 | 247, 261, 139, 371, 385 |
| 247, 261, 139, 53, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 247 x 261 x 139 x 53 x 55 = 731389719060
Therefore, the lowest common multiple of 988,522,556,371,770 is 731389719060.
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.
988 x 522 x 556 x 371 x 770 = 81915648534720
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
556 : 1, 2, 4, 139, 278, 556
371 : 1, 7, 53, 371
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,522,556,371,770, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
522:2x 3x 3x 29
556:2x 2x 139
371:7x 53
770:2x 5x 7x 11
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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 81915648534720/(1x112)
LCM = 81915648534720/112
LCM = 731389719060
Thus, we can understand that the LCM of 988,522,556,371,770 is 731389719060.
