Given numbers are 985, 687, 879, 121
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(985, 687) = 676695
GCD(985, 687) = ( 985 x 687 ) / 676695
= 985 / 687
= 985
Step2:
LCM(1, 879) = 879
GCD(1, 879) = ( 1 x 879 ) / 879
= 1 / 879
= 1
Step3:
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
= 1 / 121
= 1
So, Greatest Common Divisor of 985, 687, 879, 121 is 1
