Given numbers are 780, 630, 212, 220

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

Apply this formula for all numbers.

Step1:

LCM(780, 630) = 16380

GCD(780, 630) = ( 780 x 630 ) / 16380

= 780 / 630

= 780

Step2:

LCM(30, 212) = 3180

GCD(30, 212) = ( 30 x 212 ) / 3180

= 30 / 212

= 30

Step3:

LCM(2, 220) = 220

GCD(2, 220) = ( 2 x 220 ) / 220

= 2 / 220

= 2

So, Greatest Common Divisor of 780, 630, 212, 220 is 2
