Given numbers are 212, 689, 345, 785

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

Apply this formula for all numbers.

Step1:

LCM(212, 689) = 2756

GCD(212, 689) = ( 212 x 689 ) / 2756

= 212 / 689

= 212

Step2:

LCM(53, 345) = 18285

GCD(53, 345) = ( 53 x 345 ) / 18285

= 53 / 345

= 53

Step3:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

So, Greatest Common Divisor of 212, 689, 345, 785 is 1
