Find LCM of 398,988,495,304,451 with Prime Factorization
2 | 398, 988, 495, 304, 451 |
2 | 199, 494, 495, 152, 451 |
11 | 199, 247, 495, 76, 451 |
19 | 199, 247, 45, 76, 41 |
199, 13, 45, 4, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 199 x 13 x 45 x 4 x 41 = 15960962160
Therefore, the lowest common multiple of 398,988,495,304,451 is 15960962160.
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.
398 x 988 x 495 x 304 x 451 = 26686728731520
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.
398 : 1, 2, 199, 398
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,988,495,304,451, is 1.
Now, the common factors can be found like this.
398:2x 199
988:2x 2x 13x 19
495:3x 3x 5x 11
304:2x 2x 2x 2x 19
451:11x 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 2x 2x 11x 19 = 1672
Therefore, the value for common factors is 1672.
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 = 26686728731520/(1x1672)
LCM = 26686728731520/1672
LCM = 15960962160
Thus, we can understand that the LCM of 398,988,495,304,451 is 15960962160.
