The LCM of 238,504,938,856 is 61423992.
Find LCM of 238,504,938,856 with Prime Factorization
| 2 | 238, 504, 938, 856 |
| 2 | 119, 252, 469, 428 |
| 2 | 119, 126, 469, 214 |
| 7 | 119, 63, 469, 107 |
| 17, 9, 67, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 17 x 9 x 67 x 107 = 61423992
Therefore, the lowest common multiple of 238,504,938,856 is 61423992.
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.
238 x 504 x 938 x 856 = 96312819456
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.
238 : 1, 2, 7, 14, 17, 34, 119, 238
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
938 : 1, 2, 7, 14, 67, 134, 469, 938
856 : 1, 2, 4, 8, 107, 214, 428, 856
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,504,938,856, is 2.
Now, the common factors can be found like this.
238:2x 7x 17
504:2x 2x 2x 3x 3x 7
938:2x 7x 67
856:2x 2x 2x 107
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 7x 7 = 784
Therefore, the value for common factors is 784.
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 = 96312819456/(2x784)
LCM = 96312819456/1568
LCM = 61423992
Thus, we can understand that the LCM of 238,504,938,856 is 61423992.
