The LCM of 849,936,689,368 is 645796944.
Find LCM of 849,936,689,368 with Prime Factorization
| 2 | 849, 936, 689, 368 |
| 2 | 849, 468, 689, 184 |
| 2 | 849, 234, 689, 92 |
| 3 | 849, 117, 689, 46 |
| 13 | 283, 39, 689, 46 |
| 283, 3, 53, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 283 x 3 x 53 x 46 = 645796944
Therefore, the lowest common multiple of 849,936,689,368 is 645796944.
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.
849 x 936 x 689 x 368 = 201488646528
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.
849 : 1, 3, 283, 849
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
689 : 1, 13, 53, 689
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 849,936,689,368, is 1.
Now, the common factors can be found like this.
849:3x 283
936:2x 2x 2x 3x 3x 13
689:13x 53
368:2x 2x 2x 2x 23
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 3x 13 = 312
Therefore, the value for common factors is 312.
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 = 201488646528/(1x312)
LCM = 201488646528/312
LCM = 645796944
Thus, we can understand that the LCM of 849,936,689,368 is 645796944.
