Given numbers are 209, 535, 581, 491
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(209, 535) = 111815
GCD(209, 535) = ( 209 x 535 ) / 111815
= 209 / 535
= 209
Step2:
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
= 1 / 581
= 1
Step3:
LCM(1, 491) = 491
GCD(1, 491) = ( 1 x 491 ) / 491
= 1 / 491
= 1
So, Greatest Common Divisor of 209, 535, 581, 491 is 1
