Given numbers are 234,672,398,492
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 234,672,398,492 is 213831072.
Find LCM of 234,672,398,492 with Prime Factorization
| 2 | 234, 672, 398, 492 |
| 2 | 117, 336, 199, 246 |
| 3 | 117, 168, 199, 123 |
| 39, 56, 199, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 39 x 56 x 199 x 41 = 213831072
Therefore, the lowest common multiple of 234,672,398,492 is 213831072.
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.
234 x 672 x 398 x 492 = 30791674368
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.
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
398 : 1, 2, 199, 398
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 234,672,398,492, is 2.
Now, the common factors can be found like this.
234:2x 3x 3x 13
672:2x 2x 2x 2x 2x 3x 7
398:2x 199
492:2x 2x 3x 41
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 3 = 72
Therefore, the value for common factors is 72.
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 = 30791674368/(2x72)
LCM = 30791674368/144
LCM = 213831072
Thus, we can understand that the LCM of 234,672,398,492 is 213831072.
