Since 43 is a factor of 86, it is automatically the GCF.
43
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 2.
The GCF is 1.

43 X 2 equals 86. 43 is a prime number. 43 is the GCF of 43 and 86.
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
The GCF is 43.
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 of 86 and 30 is 2 just. You are left with 43 and 15 respectively. 43 and 15 don't have any further factors in common aside from 1.
The GCF of 86 and 154 is 2. 86=2x43 154 = 2x7x11 Now the GCF is 2 since 43 does not occur in the prime factorization of 154 and 7 and 11 do not appear in the prime factorization of 86.
The greatest factor is 86 which is a factor of 86, though not of 44. The greatest COMMON factor, though not requested, is 2.
53 is already prime. 2 x 43 = 86 No common prime factors; the GCF is 1.
2 x 43 = 86 2 x 7 x 11 = 154 The GCF is 2.
The GCF of 36 and 86 is 2. The prime factorization of 36 is 2*2*3*3 The prime factorization of 86 is 2*43 So the GCF is 2.
Factors of 27: 1, 3, 9, 27 Factors of 86: 1, 2, 43, 86 GCF (27, 86) = 1
The LCM is 86.
