GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 588) = 5292
GCD(189, 588) = ( 189 x 588 ) / 5292
= 189 / 588
= 189
Step2:
LCM(21, 242) = 5082
GCD(21, 242) = ( 21 x 242 ) / 5082
= 21 / 242
= 21
Step3:
LCM(1, 549) = 549
GCD(1, 549) = ( 1 x 549 ) / 549
= 1 / 549
= 1
So, Greatest Common Divisor of 189, 588, 242, 549 is 1
