GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(977, 428) = 418156
GCD(977, 428) = ( 977 x 428 ) / 418156
= 977 / 428
= 977
Step2:
LCM(1, 775) = 775
GCD(1, 775) = ( 1 x 775 ) / 775
= 1 / 775
= 1
Step3:
LCM(1, 289) = 289
GCD(1, 289) = ( 1 x 289 ) / 289
= 1 / 289
= 1
So, Greatest Common Divisor of 977, 428, 775, 289 is 1
