Given numbers are 691, 397, 951, 225

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

Apply this formula for all numbers.

Step1:

LCM(691, 397) = 274327

GCD(691, 397) = ( 691 x 397 ) / 274327

= 691 / 397

= 691

Step2:

LCM(1, 951) = 951

GCD(1, 951) = ( 1 x 951 ) / 951

= 1 / 951

= 1

Step3:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

So, Greatest Common Divisor of 691, 397, 951, 225 is 1
