Given numbers are 660, 649, 778, 269
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 649) = 38940
GCD(660, 649) = ( 660 x 649 ) / 38940
= 660 / 649
= 660
Step2:
LCM(11, 778) = 8558
GCD(11, 778) = ( 11 x 778 ) / 8558
= 11 / 778
= 11
Step3:
LCM(1, 269) = 269
GCD(1, 269) = ( 1 x 269 ) / 269
= 1 / 269
= 1
So, Greatest Common Divisor of 660, 649, 778, 269 is 1
