GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 459) = 3213
GCD(189, 459) = ( 189 x 459 ) / 3213
= 189 / 459
= 189
Step2:
LCM(27, 354) = 3186
GCD(27, 354) = ( 27 x 354 ) / 3186
= 27 / 354
= 27
Step3:
LCM(3, 820) = 2460
GCD(3, 820) = ( 3 x 820 ) / 2460
= 3 / 820
= 3
So, Greatest Common Divisor of 189, 459, 354, 820 is 1
