Given numbers are 639, 537, 455, 291

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

Apply this formula for all numbers.

Step1:

LCM(639, 537) = 114381

GCD(639, 537) = ( 639 x 537 ) / 114381

= 639 / 537

= 639

Step2:

LCM(3, 455) = 1365

GCD(3, 455) = ( 3 x 455 ) / 1365

= 3 / 455

= 3

Step3:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

So, Greatest Common Divisor of 639, 537, 455, 291 is 1
