Find LCM of 924,434,428,661,768 with Prime Factorization
| 2 | 924, 434, 428, 661, 768 |
| 2 | 462, 217, 214, 661, 384 |
| 3 | 231, 217, 107, 661, 192 |
| 7 | 77, 217, 107, 661, 64 |
| 11, 31, 107, 661, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 31 x 107 x 661 x 64 = 129657868032
Therefore, the lowest common multiple of 924,434,428,661,768 is 129657868032.
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 434 x 428 x 661 x 768 = 87130087317504
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
434 : 1, 2, 7, 14, 31, 62, 217, 434
428 : 1, 2, 4, 107, 214, 428
661 : 1, 661
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,434,428,661,768, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
434:2x 7x 31
428:2x 2x 107
661:661
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 2x 2x 3x 7 = 672
Therefore, the value for common factors is 672.
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 = 87130087317504/(1x672)
LCM = 87130087317504/672
LCM = 129657868032
Thus, we can understand that the LCM of 924,434,428,661,768 is 129657868032.
