The LCM of 924,856,133,987 is 176578248.
Find LCM of 924,856,133,987 with Prime Factorization
| 2 | 924, 856, 133, 987 |
| 2 | 462, 428, 133, 987 |
| 3 | 231, 214, 133, 987 |
| 7 | 77, 214, 133, 329 |
| 11, 214, 19, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 214 x 19 x 47 = 176578248
Therefore, the lowest common multiple of 924,856,133,987 is 176578248.
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 856 x 133 x 987 = 103828009824
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
856 : 1, 2, 4, 8, 107, 214, 428, 856
133 : 1, 7, 19, 133
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,856,133,987, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
856:2x 2x 2x 107
133:7x 19
987:3x 7x 47
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 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 103828009824/(1x588)
LCM = 103828009824/588
LCM = 176578248
Thus, we can understand that the LCM of 924,856,133,987 is 176578248.
