Given numbers are 843,279,394,378
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,279,394,378 is 648673326.
Find LCM of 843,279,394,378 with Prime Factorization
2 | 843, 279, 394, 378 |
3 | 843, 279, 197, 189 |
3 | 281, 93, 197, 63 |
281, 31, 197, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 281 x 31 x 197 x 21 = 648673326
Therefore, the lowest common multiple of 843,279,394,378 is 648673326.
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.
843 x 279 x 394 x 378 = 35028359604
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.
843 : 1, 3, 281, 843
279 : 1, 3, 9, 31, 93, 279
394 : 1, 2, 197, 394
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,279,394,378, is 1.
Now, the common factors can be found like this.
843:3x 281
279:3x 3x 31
394:2x 197
378:2x 3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 35028359604/(1x54)
LCM = 35028359604/54
LCM = 648673326
Thus, we can understand that the LCM of 843,279,394,378 is 648673326.
