The LCM of 389,715,862,451,338 is 127788013210.
Find LCM of 389,715,862,451,338 with Prime Factorization
| 2 | 389, 715, 862, 451, 338 |
| 11 | 389, 715, 431, 451, 169 |
| 13 | 389, 65, 431, 41, 169 |
| 389, 5, 431, 41, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 389 x 5 x 431 x 41 x 13 = 127788013210
Therefore, the lowest common multiple of 389,715,862,451,338 is 127788013210.
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.
389 x 715 x 862 x 451 x 338 = 36547371778060
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.
389 : 1, 389
715 : 1, 5, 11, 13, 55, 65, 143, 715
862 : 1, 2, 431, 862
451 : 1, 11, 41, 451
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,715,862,451,338, is 1.
Now, the common factors can be found like this.
389:389
715:5x 11x 13
862:2x 431
451:11x 41
338:2x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 13 = 286
Therefore, the value for common factors is 286.
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 = 36547371778060/(1x286)
LCM = 36547371778060/286
LCM = 127788013210
Thus, we can understand that the LCM of 389,715,862,451,338 is 127788013210.
