Given numbers are 191, 505, 688, 453

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

Apply this formula for all numbers.

Step1:

LCM(191, 505) = 96455

GCD(191, 505) = ( 191 x 505 ) / 96455

= 191 / 505

= 191

Step2:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

Step3:

LCM(1, 453) = 453

GCD(1, 453) = ( 1 x 453 ) / 453

= 1 / 453

= 1

So, Greatest Common Divisor of 191, 505, 688, 453 is 1
