Given numbers are 660, 284, 720, 259
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 284) = 46860
GCD(660, 284) = ( 660 x 284 ) / 46860
= 660 / 284
= 660
Step2:
LCM(4, 720) = 720
GCD(4, 720) = ( 4 x 720 ) / 720
= 4 / 720
= 4
Step3:
LCM(4, 259) = 1036
GCD(4, 259) = ( 4 x 259 ) / 1036
= 4 / 259
= 4
So, Greatest Common Divisor of 660, 284, 720, 259 is 1
