Given numbers are 648, 772, 215, 111

The list of prime factors of all numbers are

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 772 are 2 x 2 x 193

Prime factors of 215 are 5 x 43

Prime factors of 111 are 3 x 37

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 648, 772, 215, 111

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(648, 772) = 125064

GCD(648, 772) = ( 648 x 772 ) / 125064

= 648 / 772

= 648

Step2:

LCM(4, 215) = 860

GCD(4, 215) = ( 4 x 215 ) / 860

= 4 / 215

= 4

Step3:

LCM(1, 111) = 111

GCD(1, 111) = ( 1 x 111 ) / 111

= 1 / 111

= 1

So, Greatest Common Divisor of 648, 772, 215, 111 is 1
