Given numbers are 780, 868, 27, 210

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

Apply this formula for all numbers.

Step1:

LCM(780, 868) = 169260

GCD(780, 868) = ( 780 x 868 ) / 169260

= 780 / 868

= 780

Step2:

LCM(4, 27) = 108

GCD(4, 27) = ( 4 x 27 ) / 108

= 4 / 27

= 4

Step3:

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

= 1 / 210

= 1

So, Greatest Common Divisor of 780, 868, 27, 210 is 1
