Find LCM of 924,165,210,778 with Prime Factorization
| 2 | 924, 165, 210, 778 |
| 3 | 462, 165, 105, 389 |
| 5 | 154, 55, 35, 389 |
| 7 | 154, 11, 7, 389 |
| 11 | 22, 11, 1, 389 |
| 2, 1, 1, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 11 x 2 x 1 x 1 x 389 = 1797180
Therefore, the lowest common multiple of 924,165,210,778 is 1797180.
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.
924 x 165 x 210 x 778 = 24908914800
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.
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
165 : 1, 3, 5, 11, 15, 33, 55, 165
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,165,210,778, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
165:3x 5x 11
210:2x 3x 5x 7
778:2x 389
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 3x 5x 7x 11 = 13860
Therefore, the value for common factors is 13860.
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 = 24908914800/(1x13860)
LCM = 24908914800/13860
LCM = 1797180
Thus, we can understand that the LCM of 924,165,210,778 is 1797180.
