The LCM of 289,561,492,732 is 95408148.
Find LCM of 289,561,492,732 with Prime Factorization
2 | 289, 561, 492, 732 |
2 | 289, 561, 246, 366 |
3 | 289, 561, 123, 183 |
17 | 289, 187, 41, 61 |
17, 11, 41, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 17 x 11 x 41 x 61 = 95408148
Therefore, the lowest common multiple of 289,561,492,732 is 95408148.
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.
289 x 561 x 492 x 732 = 58389786576
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.
289 : 1, 17, 289
561 : 1, 3, 11, 17, 33, 51, 187, 561
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,561,492,732, is 1.
Now, the common factors can be found like this.
289:17x 17
561:3x 11x 17
492:2x 2x 3x 41
732:2x 2x 3x 61
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 17 = 612
Therefore, the value for common factors is 612.
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 = 58389786576/(1x612)
LCM = 58389786576/612
LCM = 95408148
Thus, we can understand that the LCM of 289,561,492,732 is 95408148.
