Given numbers are 645, 208, 985, 519

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

Apply this formula for all numbers.

Step1:

LCM(645, 208) = 134160

GCD(645, 208) = ( 645 x 208 ) / 134160

= 645 / 208

= 645

Step2:

LCM(1, 985) = 985

GCD(1, 985) = ( 1 x 985 ) / 985

= 1 / 985

= 1

Step3:

LCM(1, 519) = 519

GCD(1, 519) = ( 1 x 519 ) / 519

= 1 / 519

= 1

So, Greatest Common Divisor of 645, 208, 985, 519 is 1
