The LCM of 242,385,340,978,102 is 140822220.
Find LCM of 242,385,340,978,102 with Prime Factorization
| 2 | 242, 385, 340, 978, 102 |
| 3 | 121, 385, 170, 489, 51 |
| 5 | 121, 385, 170, 163, 17 |
| 11 | 121, 77, 34, 163, 17 |
| 17 | 11, 7, 34, 163, 17 |
| 11, 7, 2, 163, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 17 x 11 x 7 x 2 x 163 x 1 = 140822220
Therefore, the lowest common multiple of 242,385,340,978,102 is 140822220.
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.
242 x 385 x 340 x 978 x 102 = 3160050616800
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.
242 : 1, 2, 11, 22, 121, 242
385 : 1, 5, 7, 11, 35, 55, 77, 385
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
978 : 1, 2, 3, 6, 163, 326, 489, 978
102 : 1, 2, 3, 6, 17, 34, 51, 102
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,385,340,978,102, is 1.
Now, the common factors can be found like this.
242:2x 11x 11
385:5x 7x 11
340:2x 2x 5x 17
978:2x 3x 163
102:2x 3x 17
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 5x 11x 17 = 22440
Therefore, the value for common factors is 22440.
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 = 3160050616800/(1x22440)
LCM = 3160050616800/22440
LCM = 140822220
Thus, we can understand that the LCM of 242,385,340,978,102 is 140822220.
