Given numbers are 655, 840, 195, 435

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

Apply this formula for all numbers.

Step1:

LCM(655, 840) = 110040

GCD(655, 840) = ( 655 x 840 ) / 110040

= 655 / 840

= 655

Step2:

LCM(5, 195) = 195

GCD(5, 195) = ( 5 x 195 ) / 195

= 5 / 195

= 5

Step3:

LCM(5, 435) = 435

GCD(5, 435) = ( 5 x 435 ) / 435

= 5 / 435

= 5

So, Greatest Common Divisor of 655, 840, 195, 435 is 5
