Given numbers are 660, 220, 997, 517
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 220) = 660
GCD(660, 220) = ( 660 x 220 ) / 660
= 660 / 220
= 660
Step2:
LCM(220, 997) = 219340
GCD(220, 997) = ( 220 x 997 ) / 219340
= 220 / 997
= 220
Step3:
LCM(1, 517) = 517
GCD(1, 517) = ( 1 x 517 ) / 517
= 1 / 517
= 1
So, Greatest Common Divisor of 660, 220, 997, 517 is 1
