Given numbers are 801,485,701,771,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 801,485,701,771,978 is 22816183239270.
Find LCM of 801,485,701,771,978 with Prime Factorization
3 | 801, 485, 701, 771, 978 |
267, 485, 701, 257, 326 |
Multiply the prime numbers at the bottom and the left side.
3 x 267 x 485 x 701 x 257 x 326 = 22816183239270
Therefore, the lowest common multiple of 801,485,701,771,978 is 22816183239270.
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.
801 x 485 x 701 x 771 x 978 = 205345649153430
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.
801 : 1, 3, 9, 89, 267, 801
485 : 1, 5, 97, 485
701 : 1, 701
771 : 1, 3, 257, 771
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,485,701,771,978, is 1.
Now, the common factors can be found like this.
801:3x 3x 89
485:5x 97
701:701
771:3x 257
978:2x 3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 205345649153430/(1x9)
LCM = 205345649153430/9
LCM = 22816183239270
Thus, we can understand that the LCM of 801,485,701,771,978 is 22816183239270.
