Given numbers are 977, 139, 602, 428
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(977, 139) = 135803
GCD(977, 139) = ( 977 x 139 ) / 135803
= 977 / 139
= 977
Step2:
LCM(1, 602) = 602
GCD(1, 602) = ( 1 x 602 ) / 602
= 1 / 602
= 1
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 977, 139, 602, 428 is 1
