Find LCM of 238,965,561,521,798 with Prime Factorization
| 2 | 238, 965, 561, 521, 798 |
| 3 | 119, 965, 561, 521, 399 |
| 7 | 119, 965, 187, 521, 133 |
| 17 | 17, 965, 187, 521, 19 |
| 1, 965, 11, 521, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 1 x 965 x 11 x 521 x 19 = 75025609890
Therefore, the lowest common multiple of 238,965,561,521,798 is 75025609890.
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.
238 x 965 x 561 x 521 x 798 = 53568285461460
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.
238 : 1, 2, 7, 14, 17, 34, 119, 238
965 : 1, 5, 193, 965
561 : 1, 3, 11, 17, 33, 51, 187, 561
521 : 1, 521
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,965,561,521,798, is 1.
Now, the common factors can be found like this.
238:2x 7x 17
965:5x 193
561:3x 11x 17
521:521
798:2x 3x 7x 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 3x 7x 17 = 714
Therefore, the value for common factors is 714.
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 = 53568285461460/(1x714)
LCM = 53568285461460/714
LCM = 75025609890
Thus, we can understand that the LCM of 238,965,561,521,798 is 75025609890.
