Given numbers are 986,972,432,508
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 986,972,432,508 is 243431568.
Find LCM of 986,972,432,508 with Prime Factorization
| 2 | 986, 972, 432, 508 |
| 2 | 493, 486, 216, 254 |
| 3 | 493, 243, 108, 127 |
| 3 | 493, 81, 36, 127 |
| 3 | 493, 27, 12, 127 |
| 493, 9, 4, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 493 x 9 x 4 x 127 = 243431568
Therefore, the lowest common multiple of 986,972,432,508 is 243431568.
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.
986 x 972 x 432 x 508 = 210324874752
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
508 : 1, 2, 4, 127, 254, 508
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,972,432,508, is 2.
Now, the common factors can be found like this.
986:2x 17x 29
972:2x 2x 3x 3x 3x 3x 3
432:2x 2x 2x 2x 3x 3x 3
508:2x 2x 127
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 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 210324874752/(2x432)
LCM = 210324874752/864
LCM = 243431568
Thus, we can understand that the LCM of 986,972,432,508 is 243431568.
