Given numbers are 128, 548, 989, 356

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

Apply this formula for all numbers.

Step1:

LCM(128, 548) = 17536

GCD(128, 548) = ( 128 x 548 ) / 17536

= 128 / 548

= 128

Step2:

LCM(4, 989) = 3956

GCD(4, 989) = ( 4 x 989 ) / 3956

= 4 / 989

= 4

Step3:

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

= 1 / 356

= 1

So, Greatest Common Divisor of 128, 548, 989, 356 is 1
