Given numbers are 998,247,738,156,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,247,738,156,974 is 88595735436.
Find LCM of 998,247,738,156,974 with Prime Factorization
| 2 | 998, 247, 738, 156, 974 |
| 3 | 499, 247, 369, 78, 487 |
| 13 | 499, 247, 123, 26, 487 |
| 499, 19, 123, 2, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 499 x 19 x 123 x 2 x 487 = 88595735436
Therefore, the lowest common multiple of 998,247,738,156,974 is 88595735436.
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.
998 x 247 x 738 x 156 x 974 = 27641869456032
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.
998 : 1, 2, 499, 998
247 : 1, 13, 19, 247
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,247,738,156,974, is 1.
Now, the common factors can be found like this.
998:2x 499
247:13x 19
738:2x 3x 3x 41
156:2x 2x 3x 13
974:2x 487
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 13 = 312
Therefore, the value for common factors is 312.
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 = 27641869456032/(1x312)
LCM = 27641869456032/312
LCM = 88595735436
Thus, we can understand that the LCM of 998,247,738,156,974 is 88595735436.
