Given numbers are 840, 497, 991, 193

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

Apply this formula for all numbers.

Step1:

LCM(840, 497) = 59640

GCD(840, 497) = ( 840 x 497 ) / 59640

= 840 / 497

= 840

Step2:

LCM(7, 991) = 6937

GCD(7, 991) = ( 7 x 991 ) / 6937

= 7 / 991

= 7

Step3:

LCM(1, 193) = 193

GCD(1, 193) = ( 1 x 193 ) / 193

= 1 / 193

= 1

So, Greatest Common Divisor of 840, 497, 991, 193 is 1
