Given numbers are 812, 870, 779, 436

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

Apply this formula for all numbers.

Step1:

LCM(812, 870) = 12180

GCD(812, 870) = ( 812 x 870 ) / 12180

= 812 / 870

= 812

Step2:

LCM(58, 779) = 45182

GCD(58, 779) = ( 58 x 779 ) / 45182

= 58 / 779

= 58

Step3:

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

= 1 / 436

= 1

So, Greatest Common Divisor of 812, 870, 779, 436 is 1
