Given numbers are 189, 540, 639, 520

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

Apply this formula for all numbers.

Step1:

LCM(189, 540) = 3780

GCD(189, 540) = ( 189 x 540 ) / 3780

= 189 / 540

= 189

Step2:

LCM(27, 639) = 1917

GCD(27, 639) = ( 27 x 639 ) / 1917

= 27 / 639

= 27

Step3:

LCM(9, 520) = 4680

GCD(9, 520) = ( 9 x 520 ) / 4680

= 9 / 520

= 9

So, Greatest Common Divisor of 189, 540, 639, 520 is 1
