The LCM of 521,969,768,374 is 1421654784.
Find LCM of 521,969,768,374 with Prime Factorization
| 2 | 521, 969, 768, 374 |
| 3 | 521, 969, 384, 187 |
| 17 | 521, 323, 128, 187 |
| 521, 19, 128, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 521 x 19 x 128 x 11 = 1421654784
Therefore, the lowest common multiple of 521,969,768,374 is 1421654784.
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.
521 x 969 x 768 x 374 = 145008787968
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.
521 : 1, 521
969 : 1, 3, 17, 19, 51, 57, 323, 969
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
374 : 1, 2, 11, 17, 22, 34, 187, 374
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,969,768,374, is 1.
Now, the common factors can be found like this.
521:521
969:3x 17x 19
768:2x 2x 2x 2x 2x 2x 2x 2x 3
374:2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 145008787968/(1x102)
LCM = 145008787968/102
LCM = 1421654784
Thus, we can understand that the LCM of 521,969,768,374 is 1421654784.
