GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 319) = 22649
GCD(781, 319) = ( 781 x 319 ) / 22649
= 781 / 319
= 781
Step2:
LCM(11, 605) = 605
GCD(11, 605) = ( 11 x 605 ) / 605
= 11 / 605
= 11
Step3:
LCM(11, 220) = 220
GCD(11, 220) = ( 11 x 220 ) / 220
= 11 / 220
= 11
So, Greatest Common Divisor of 781, 319, 605, 220 is 11
