It is just 1
First, Its the gcf not the gfc Gcf : | 86 129 215 129 is a prime number so GCF= 1 LCM: 86 x 129x 215 =2385210
The GCF is 43.
The greatest factor is 86 which is a factor of 86, though not of 44. The greatest COMMON factor, though not requested, is 2.
The factors of 86 are:1, 2, 43, 86The factors of 129 are:1, 3, 43, 129The factors of 215 are:1, 5, 43, 215The common factors are:1, 43The Greatest Common Factor (GCF) is: 43
% rate:= 129/86 * 100%= 1.5 * 100%= 150%
The gcf of 43 and 129 is 43, so the two digit number must be 43; howeverthe gcf of 86 and 129 is also 43, so the two digit number must be 86; howeverthe gcf of 22 and 86 is only 2 and the gcf of 22 and 43 is only 1, no neither 43 nor 86 has a gcf of 43!Hint:You cannot have a COMMON factor with only onenumber - common implies at least two numbers.The greatest COMMON factor is the largest number that divides all the numbers and depends upon all the numbers - it makes no sense to ask for the greatest COMMON factor of a single number.
The GCF is 86.
The GCF is 2.
129= 86 x 3/2 . If you want only 4s then 129 = 86 x(4+4+4)/(4+4) etc
The GCF for 86 5 is 1.
The GCF of 86 and 36 is 2.
The GCF is 2.
