Given numbers are 189, 898, 989, 545

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

Apply this formula for all numbers.

Step1:

LCM(189, 898) = 169722

GCD(189, 898) = ( 189 x 898 ) / 169722

= 189 / 898

= 189

Step2:

LCM(1, 989) = 989

GCD(1, 989) = ( 1 x 989 ) / 989

= 1 / 989

= 1

Step3:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

So, Greatest Common Divisor of 189, 898, 989, 545 is 1
