Given numbers are 710, 639, 434, 645

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

Apply this formula for all numbers.

Step1:

LCM(710, 639) = 6390

GCD(710, 639) = ( 710 x 639 ) / 6390

= 710 / 639

= 710

Step2:

LCM(71, 434) = 30814

GCD(71, 434) = ( 71 x 434 ) / 30814

= 71 / 434

= 71

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 710, 639, 434, 645 is 1
