Given numbers are 570, 209, 309, 163
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(570, 209) = 6270
GCD(570, 209) = ( 570 x 209 ) / 6270
= 570 / 209
= 570
Step2:
LCM(19, 309) = 5871
GCD(19, 309) = ( 19 x 309 ) / 5871
= 19 / 309
= 19
Step3:
LCM(1, 163) = 163
GCD(1, 163) = ( 1 x 163 ) / 163
= 1 / 163
= 1
So, Greatest Common Divisor of 570, 209, 309, 163 is 1
