The LCM of 238,252,256,437,705 is 28156504320.
Find LCM of 238,252,256,437,705 with Prime Factorization
| 2 | 238, 252, 256, 437, 705 |
| 2 | 119, 126, 128, 437, 705 |
| 3 | 119, 63, 64, 437, 705 |
| 7 | 119, 21, 64, 437, 235 |
| 17, 3, 64, 437, 235 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 17 x 3 x 64 x 437 x 235 = 28156504320
Therefore, the lowest common multiple of 238,252,256,437,705 is 28156504320.
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 252 x 256 x 437 x 705 = 4730292725760
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
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
437 : 1, 19, 23, 437
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,252,256,437,705, is 1.
Now, the common factors can be found like this.
238:2x 7x 17
252:2x 2x 3x 3x 7
256:2x 2x 2x 2x 2x 2x 2x 2
437:19x 23
705:3x 5x 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 2x 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 4730292725760/(1x168)
LCM = 4730292725760/168
LCM = 28156504320
Thus, we can understand that the LCM of 238,252,256,437,705 is 28156504320.
