Given numbers are 865, 535, 109, 785

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

Apply this formula for all numbers.

Step1:

LCM(865, 535) = 92555

GCD(865, 535) = ( 865 x 535 ) / 92555

= 865 / 535

= 865

Step2:

LCM(5, 109) = 545

GCD(5, 109) = ( 5 x 109 ) / 545

= 5 / 109

= 5

Step3:

LCM(1, 785) = 785

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

= 1 / 785

= 1

So, Greatest Common Divisor of 865, 535, 109, 785 is 1
