Given numbers are 212, 356, 434, 691

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

Apply this formula for all numbers.

Step1:

LCM(212, 356) = 18868

GCD(212, 356) = ( 212 x 356 ) / 18868

= 212 / 356

= 212

Step2:

LCM(4, 434) = 868

GCD(4, 434) = ( 4 x 434 ) / 868

= 4 / 434

= 4

Step3:

LCM(2, 691) = 1382

GCD(2, 691) = ( 2 x 691 ) / 1382

= 2 / 691

= 2

So, Greatest Common Divisor of 212, 356, 434, 691 is 1
