Given numbers are 355, 785, 781, 195

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

Apply this formula for all numbers.

Step1:

LCM(355, 785) = 55735

GCD(355, 785) = ( 355 x 785 ) / 55735

= 355 / 785

= 355

Step2:

LCM(5, 781) = 3905

GCD(5, 781) = ( 5 x 781 ) / 3905

= 5 / 781

= 5

Step3:

LCM(1, 195) = 195

GCD(1, 195) = ( 1 x 195 ) / 195

= 1 / 195

= 1

So, Greatest Common Divisor of 355, 785, 781, 195 is 1
