You should be doing this unaided as I am sure it is the Scottish Junior Maths Challenge!
Eleven has no such factor.
The greatest common FACTOR of 90 and 108 is 18. The LEAST common multiple is 540. There can be no greatest common multiple since double that number will be a greater common multiple.
No, the lesser.
11*10*9*8*7*6*5*4*3*2*1Alternative:11 factorial equals 39916800. Considering 39916800 X 1, then 39916800 would be the greatest factor. If you don't want to consider 1 a factor, then it would be 19958400, which is one half of 39916800. The question does not specify prime factors. I think the greatest prime factor would have to be 11, since any factor greater than 11 would have to be the product of some combination of the numbers between 10 and 1.
lcm(16, 20) is 80.There is NO greatest common multiple, for whatever multiple of their LCM you give, I can always add another 80 and get an even greater common multiple.Mefinx you meant their greatest common FACTOR, which is 4.
There is no greatest common multiple: for whatever value you say is the greatest I can always add their lowest common multiple and get an even greater common multiple.There is a greatest common FACTOR and a LOWEST common multiple:gcf(36, 25) = 1lcm(36, 25) = 900
There is no greatest common multiple: for whatever value you say is the greatest I can always add their lowest common multiple and get an even greater common multiple.There is a greatest common FACTOR and a LOWEST common multiple:gcf(89, 35) = 1lcm(89, 35) = 3115
There is no greatest common multiple: for whatever value you say is the greatest I can always add their lowest common multiple and get an even greater common multiple.There is a greatest common FACTOR and a LOWEST common multiple:gcf(54, 108) = 54lcm(54, 108) = 108
There is no greatest common multiple: for whatever value you say is the greatest I can always add their lowest common multiple and get an even greater common multiple.There is a greatest common FACTOR and a LOWEST common multiple:gcf(5, 6) = 1lcm(5, 6) = 30
That's not the factorial of any number. For a start, the factorial of any number greater than or equal to 2 is even, because of the factor 2. The factorial of any number greater or equal to five ends with 0. Another answer: I suspect the questioner meant to ask how to write 8*7*6*5*4*3*2*1 as a factorial. If so, then the answer is "8!"
no
The greatest common factor is 2 and the least common multiple is also 2.
