Find LCM of 777,381,408,158,492 with Prime Factorization
2 | 777, 381, 408, 158, 492 |
2 | 777, 381, 204, 79, 246 |
3 | 777, 381, 102, 79, 123 |
259, 127, 34, 79, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 259 x 127 x 34 x 79 x 41 = 43468494216
Therefore, the lowest common multiple of 777,381,408,158,492 is 43468494216.
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.
777 x 381 x 408 x 158 x 492 = 9389194750656
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.
777 : 1, 3, 7, 21, 37, 111, 259, 777
381 : 1, 3, 127, 381
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
158 : 1, 2, 79, 158
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,381,408,158,492, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
381:3x 127
408:2x 2x 2x 3x 17
158:2x 79
492:2x 2x 3x 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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 9389194750656/(1x216)
LCM = 9389194750656/216
LCM = 43468494216
Thus, we can understand that the LCM of 777,381,408,158,492 is 43468494216.
