Given numbers are 157,722,494,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,722,494,494 is 1473602.
Find LCM of 157,722,494,494 with Prime Factorization
| 2 | 157, 722, 494, 494 |
| 13 | 157, 361, 247, 247 |
| 19 | 157, 361, 19, 19 |
| 157, 1, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 157 x 1 x 1 x 19 = 1473602
Therefore, the lowest common multiple of 157,722,494,494 is 1473602.
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.
157 x 722 x 494 x 494 = 27662456744
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.
157 : 1, 157
722 : 1, 2, 19, 38, 361, 722
494 : 1, 2, 13, 19, 26, 38, 247, 494
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,722,494,494, is 1.
Now, the common factors can be found like this.
157:157
722:2x 19x 19
494:2x 13x 19
494:2x 13x 19
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 13x 19x 19 = 18772
Therefore, the value for common factors is 18772.
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 = 27662456744/(1x18772)
LCM = 27662456744/18772
LCM = 1473602
Thus, we can understand that the LCM of 157,722,494,494 is 1473602.
