Given numbers are 530,986,754,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 530,986,754,561 is 112093410.
Find LCM of 530,986,754,561 with Prime Factorization
| 2 | 530, 986, 754, 561 |
| 17 | 265, 493, 377, 561 |
| 29 | 265, 29, 377, 33 |
| 265, 1, 13, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 29 x 265 x 1 x 13 x 33 = 112093410
Therefore, the lowest common multiple of 530,986,754,561 is 112093410.
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.
530 x 986 x 754 x 561 = 221048204520
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.
530 : 1, 2, 5, 10, 53, 106, 265, 530
986 : 1, 2, 17, 29, 34, 58, 493, 986
754 : 1, 2, 13, 26, 29, 58, 377, 754
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 530,986,754,561, is 1.
Now, the common factors can be found like this.
530:2x 5x 53
986:2x 17x 29
754:2x 13x 29
561:3x 11x 17
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 17x 29 = 1972
Therefore, the value for common factors is 1972.
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 = 221048204520/(1x1972)
LCM = 221048204520/1972
LCM = 112093410
Thus, we can understand that the LCM of 530,986,754,561 is 112093410.
