Given numbers are 780, 810, 410, 422

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

Apply this formula for all numbers.

Step1:

LCM(780, 810) = 21060

GCD(780, 810) = ( 780 x 810 ) / 21060

= 780 / 810

= 780

Step2:

LCM(30, 410) = 1230

GCD(30, 410) = ( 30 x 410 ) / 1230

= 30 / 410

= 30

Step3:

LCM(10, 422) = 2110

GCD(10, 422) = ( 10 x 422 ) / 2110

= 10 / 422

= 10

So, Greatest Common Divisor of 780, 810, 410, 422 is 2
