Find LCM of 778,385,158,165,924 with Prime Factorization
| 2 | 778, 385, 158, 165, 924 |
| 3 | 389, 385, 79, 165, 462 |
| 5 | 389, 385, 79, 55, 154 |
| 7 | 389, 77, 79, 11, 154 |
| 11 | 389, 11, 79, 11, 22 |
| 389, 1, 79, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 11 x 389 x 1 x 79 x 1 x 2 = 141977220
Therefore, the lowest common multiple of 778,385,158,165,924 is 141977220.
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.
778 x 385 x 158 x 165 x 924 = 7215282320400
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.
778 : 1, 2, 389, 778
385 : 1, 5, 7, 11, 35, 55, 77, 385
158 : 1, 2, 79, 158
165 : 1, 3, 5, 11, 15, 33, 55, 165
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,385,158,165,924, is 1.
Now, the common factors can be found like this.
778:2x 389
385:5x 7x 11
158:2x 79
165:3x 5x 11
924:2x 2x 3x 7x 11
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 3x 5x 7x 11x 11 = 50820
Therefore, the value for common factors is 50820.
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 = 7215282320400/(1x50820)
LCM = 7215282320400/50820
LCM = 141977220
Thus, we can understand that the LCM of 778,385,158,165,924 is 141977220.
