Find LCM of 338,681,636,901,788 with Prime Factorization
| 2 | 338, 681, 636, 901, 788 |
| 2 | 169, 681, 318, 901, 394 |
| 3 | 169, 681, 159, 901, 197 |
| 53 | 169, 227, 53, 901, 197 |
| 169, 227, 1, 17, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 53 x 169 x 227 x 1 x 17 x 197 = 81711808932
Therefore, the lowest common multiple of 338,681,636,901,788 is 81711808932.
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.
338 x 681 x 636 x 901 x 788 = 103937420961504
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.
338 : 1, 2, 13, 26, 169, 338
681 : 1, 3, 227, 681
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
901 : 1, 17, 53, 901
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,681,636,901,788, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
681:3x 227
636:2x 2x 3x 53
901:17x 53
788:2x 2x 197
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 53 = 1272
Therefore, the value for common factors is 1272.
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 = 103937420961504/(1x1272)
LCM = 103937420961504/1272
LCM = 81711808932
Thus, we can understand that the LCM of 338,681,636,901,788 is 81711808932.
