Given numbers are 691, 497, 213, 219

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

Apply this formula for all numbers.

Step1:

LCM(691, 497) = 343427

GCD(691, 497) = ( 691 x 497 ) / 343427

= 691 / 497

= 691

Step2:

LCM(1, 213) = 213

GCD(1, 213) = ( 1 x 213 ) / 213

= 1 / 213

= 1

Step3:

LCM(1, 219) = 219

GCD(1, 219) = ( 1 x 219 ) / 219

= 1 / 219

= 1

So, Greatest Common Divisor of 691, 497, 213, 219 is 1
