Given numbers are 189, 603, 117, 977

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

Apply this formula for all numbers.

Step1:

LCM(189, 603) = 12663

GCD(189, 603) = ( 189 x 603 ) / 12663

= 189 / 603

= 189

Step2:

LCM(9, 117) = 117

GCD(9, 117) = ( 9 x 117 ) / 117

= 9 / 117

= 9

Step3:

LCM(9, 977) = 8793

GCD(9, 977) = ( 9 x 977 ) / 8793

= 9 / 977

= 9

So, Greatest Common Divisor of 189, 603, 117, 977 is 1
