Given numbers are 397,492,631,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,492,631,894 is 18364167156.
Find LCM of 397,492,631,894 with Prime Factorization
| 2 | 397, 492, 631, 894 |
| 3 | 397, 246, 631, 447 |
| 397, 82, 631, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 397 x 82 x 631 x 149 = 18364167156
Therefore, the lowest common multiple of 397,492,631,894 is 18364167156.
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.
397 x 492 x 631 x 894 = 110185002936
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.
397 : 1, 397
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
631 : 1, 631
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,492,631,894, is 1.
Now, the common factors can be found like this.
397:397
492:2x 2x 3x 41
631:631
894:2x 3x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 110185002936/(1x6)
LCM = 110185002936/6
LCM = 18364167156
Thus, we can understand that the LCM of 397,492,631,894 is 18364167156.
