Given numbers are 972, 257, 997, 111
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(972, 257) = 249804
GCD(972, 257) = ( 972 x 257 ) / 249804
= 972 / 257
= 972
Step2:
LCM(1, 997) = 997
GCD(1, 997) = ( 1 x 997 ) / 997
= 1 / 997
= 1
Step3:
LCM(1, 111) = 111
GCD(1, 111) = ( 1 x 111 ) / 111
= 1 / 111
= 1
So, Greatest Common Divisor of 972, 257, 997, 111 is 1
