Given numbers are 770, 685, 470, 405

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

Apply this formula for all numbers.

Step1:

LCM(770, 685) = 105490

GCD(770, 685) = ( 770 x 685 ) / 105490

= 770 / 685

= 770

Step2:

LCM(5, 470) = 470

GCD(5, 470) = ( 5 x 470 ) / 470

= 5 / 470

= 5

Step3:

LCM(5, 405) = 405

GCD(5, 405) = ( 5 x 405 ) / 405

= 5 / 405

= 5

So, Greatest Common Divisor of 770, 685, 470, 405 is 5
