Find LCM of 338,272,690,676,889 with Prime Factorization
| 2 | 338, 272, 690, 676, 889 |
| 2 | 169, 136, 345, 338, 889 |
| 13 | 169, 68, 345, 169, 889 |
| 13 | 13, 68, 345, 13, 889 |
| 1, 68, 345, 1, 889 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 13 x 1 x 68 x 345 x 1 x 889 = 14098615440
Therefore, the lowest common multiple of 338,272,690,676,889 is 14098615440.
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 272 x 690 x 676 x 889 = 38122656149760
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
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,272,690,676,889, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
272:2x 2x 2x 2x 17
690:2x 3x 5x 23
676:2x 2x 13x 13
889:7x 127
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 2x 13x 13 = 2704
Therefore, the value for common factors is 2704.
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 = 38122656149760/(1x2704)
LCM = 38122656149760/2704
LCM = 14098615440
Thus, we can understand that the LCM of 338,272,690,676,889 is 14098615440.
