Given numbers are 166, 514, 646, 549
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(166, 514) = 42662
GCD(166, 514) = ( 166 x 514 ) / 42662
= 166 / 514
= 166
Step2:
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
= 2 / 646
= 2
Step3:
LCM(2, 549) = 1098
GCD(2, 549) = ( 2 x 549 ) / 1098
= 2 / 549
= 2
So, Greatest Common Divisor of 166, 514, 646, 549 is 1
