Given numbers are 494,942,978,117,751
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 494,942,978,117,751 is 85446967086.
Find LCM of 494,942,978,117,751 with Prime Factorization
| 2 | 494, 942, 978, 117, 751 |
| 3 | 247, 471, 489, 117, 751 |
| 13 | 247, 157, 163, 39, 751 |
| 19, 157, 163, 3, 751 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 19 x 157 x 163 x 3 x 751 = 85446967086
Therefore, the lowest common multiple of 494,942,978,117,751 is 85446967086.
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.
494 x 942 x 978 x 117 x 751 = 39989180596248
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.
494 : 1, 2, 13, 19, 26, 38, 247, 494
942 : 1, 2, 3, 6, 157, 314, 471, 942
978 : 1, 2, 3, 6, 163, 326, 489, 978
117 : 1, 3, 9, 13, 39, 117
751 : 1, 751
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,942,978,117,751, is 1.
Now, the common factors can be found like this.
494:2x 13x 19
942:2x 3x 157
978:2x 3x 163
117:3x 3x 13
751:751
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 3x 13 = 468
Therefore, the value for common factors is 468.
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 = 39989180596248/(1x468)
LCM = 39989180596248/468
LCM = 85446967086
Thus, we can understand that the LCM of 494,942,978,117,751 is 85446967086.
