The LCM of 238,497,381,724,697 is 95554844196.
Find LCM of 238,497,381,724,697 with Prime Factorization
| 2 | 238, 497, 381, 724, 697 |
| 7 | 119, 497, 381, 362, 697 |
| 17 | 17, 71, 381, 362, 697 |
| 1, 71, 381, 362, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 1 x 71 x 381 x 362 x 41 = 95554844196
Therefore, the lowest common multiple of 238,497,381,724,697 is 95554844196.
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 497 x 381 x 724 x 697 = 22742052918648
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
497 : 1, 7, 71, 497
381 : 1, 3, 127, 381
724 : 1, 2, 4, 181, 362, 724
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,497,381,724,697, is 1.
Now, the common factors can be found like this.
238:2x 7x 17
497:7x 71
381:3x 127
724:2x 2x 181
697:17x 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 7x 17 = 238
Therefore, the value for common factors is 238.
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 = 22742052918648/(1x238)
LCM = 22742052918648/238
LCM = 95554844196
Thus, we can understand that the LCM of 238,497,381,724,697 is 95554844196.
