The GCF is 1.
The GCF is: 5
The greatest common factor of 273 and 507 is 39.
the greatest common factor of 51 and 34 is 17 because 17 is a factor of both 51 and 34 and it happens to be the greatest.
1, 5, 107, 535
One number cannot have a GCF or an LCM. You need at least two, but there is no pair of numbers that fit those conditions.
25= 5 x 535= 5 x 7HCF = 5
The prime factors are: 5,107
HCF of 20 means the two numbers have common prime factors of 2, 2 and 5. However, LCM of 535 means that both of the numbers are odd. This cannot be the case if they have a prime factor of 2. Thus two numbers cannot have 20 as hcf and 535 as lcm.
35-535 = -500
The factors of 535 are: 1, 5, 107 & 535.
