Given numbers are 437,694,784,278,218
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,694,784,278,218 is 1801226271376.
Find LCM of 437,694,784,278,218 with Prime Factorization
| 2 | 437, 694, 784, 278, 218 |
| 437, 347, 392, 139, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 437 x 347 x 392 x 139 x 109 = 1801226271376
Therefore, the lowest common multiple of 437,694,784,278,218 is 1801226271376.
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.
437 x 694 x 784 x 278 x 218 = 14409810171008
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.
437 : 1, 19, 23, 437
694 : 1, 2, 347, 694
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
278 : 1, 2, 139, 278
218 : 1, 2, 109, 218
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,694,784,278,218, is 1.
Now, the common factors can be found like this.
437:19x 23
694:2x 347
784:2x 2x 2x 2x 7x 7
278:2x 139
218:2x 109
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 2 = 8
Therefore, the value for common factors is 8.
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 = 14409810171008/(1x8)
LCM = 14409810171008/8
LCM = 1801226271376
Thus, we can understand that the LCM of 437,694,784,278,218 is 1801226271376.
