Given numbers are 695, 215, 211, 561

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

Apply this formula for all numbers.

Step1:

LCM(695, 215) = 29885

GCD(695, 215) = ( 695 x 215 ) / 29885

= 695 / 215

= 695

Step2:

LCM(5, 211) = 1055

GCD(5, 211) = ( 5 x 211 ) / 1055

= 5 / 211

= 5

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 695, 215, 211, 561 is 1
