Given numbers are 581, 641, 212, 561
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(581, 641) = 372421
GCD(581, 641) = ( 581 x 641 ) / 372421
= 581 / 641
= 581
Step2:
LCM(1, 212) = 212
GCD(1, 212) = ( 1 x 212 ) / 212
= 1 / 212
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 581, 641, 212, 561 is 1
