The LCM of 769,381,252,188,451 is 521680977972.
Find LCM of 769,381,252,188,451 with Prime Factorization
| 2 | 769, 381, 252, 188, 451 |
| 2 | 769, 381, 126, 94, 451 |
| 3 | 769, 381, 63, 47, 451 |
| 769, 127, 21, 47, 451 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 769 x 127 x 21 x 47 x 451 = 521680977972
Therefore, the lowest common multiple of 769,381,252,188,451 is 521680977972.
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.
769 x 381 x 252 x 188 x 451 = 6260171735664
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.
769 : 1, 769
381 : 1, 3, 127, 381
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
188 : 1, 2, 4, 47, 94, 188
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,381,252,188,451, is 1.
Now, the common factors can be found like this.
769:769
381:3x 127
252:2x 2x 3x 3x 7
188:2x 2x 47
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 3 = 12
Therefore, the value for common factors is 12.
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 = 6260171735664/(1x12)
LCM = 6260171735664/12
LCM = 521680977972
Thus, we can understand that the LCM of 769,381,252,188,451 is 521680977972.
