The LCM of 307,428,771,252,893 is 1899797343948.
Find LCM of 307,428,771,252,893 with Prime Factorization
| 2 | 307, 428, 771, 252, 893 |
| 2 | 307, 214, 771, 126, 893 |
| 3 | 307, 107, 771, 63, 893 |
| 307, 107, 257, 21, 893 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 307 x 107 x 257 x 21 x 893 = 1899797343948
Therefore, the lowest common multiple of 307,428,771,252,893 is 1899797343948.
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.
307 x 428 x 771 x 252 x 893 = 22797568127376
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.
307 : 1, 307
428 : 1, 2, 4, 107, 214, 428
771 : 1, 3, 257, 771
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
893 : 1, 19, 47, 893
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 307,428,771,252,893, is 1.
Now, the common factors can be found like this.
307:307
428:2x 2x 107
771:3x 257
252:2x 2x 3x 3x 7
893:19x 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 3 = 12
Therefore, the value for common factors is 12.
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 = 22797568127376/(1x12)
LCM = 22797568127376/12
LCM = 1899797343948
Thus, we can understand that the LCM of 307,428,771,252,893 is 1899797343948.
