Find LCM of 924,821,312,663 with Prime Factorization
| 2 | 924, 821, 312, 663 |
| 2 | 462, 821, 156, 663 |
| 3 | 231, 821, 78, 663 |
| 13 | 77, 821, 26, 221 |
| 77, 821, 2, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 77 x 821 x 2 x 17 = 335302968
Therefore, the lowest common multiple of 924,821,312,663 is 335302968.
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 821 x 312 x 663 = 156921789024
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
821 : 1, 821
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,821,312,663, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
821:821
312:2x 2x 2x 3x 13
663:3x 13x 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 2x 3x 3x 13 = 468
Therefore, the value for common factors is 468.
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 = 156921789024/(1x468)
LCM = 156921789024/468
LCM = 335302968
Thus, we can understand that the LCM of 924,821,312,663 is 335302968.
