Given numbers are 780, 222, 552, 243

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

Apply this formula for all numbers.

Step1:

LCM(780, 222) = 28860

GCD(780, 222) = ( 780 x 222 ) / 28860

= 780 / 222

= 780

Step2:

LCM(6, 552) = 552

GCD(6, 552) = ( 6 x 552 ) / 552

= 6 / 552

= 6

Step3:

LCM(6, 243) = 486

GCD(6, 243) = ( 6 x 243 ) / 486

= 6 / 243

= 6

So, Greatest Common Divisor of 780, 222, 552, 243 is 3
