1 is their Highest Common Factor or Greatest Common Divisor.
Aayush is correct. But I wonder if you mean Lowest Common Multiple. That is the lowest number that both will divide evenly into without remainder. First factorise into prime factors 57 = 3 x 19 111 = 3 x 37 Then make sure you include one of each factor So the LCM is 3 x 19 x 37 = 2109
The greatest common factor of 24 and 57 is 3.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 57 and 95 is 19
Greatest common factor of 57 and 102 is 3.
