Given numbers are 991, 537, 497, 640

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

Apply this formula for all numbers.

Step1:

LCM(991, 537) = 532167

GCD(991, 537) = ( 991 x 537 ) / 532167

= 991 / 537

= 991

Step2:

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

= 1 / 497

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 991, 537, 497, 640 is 1
