Given numbers are 261, 890, 684, 469
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(261, 890) = 232290
GCD(261, 890) = ( 261 x 890 ) / 232290
= 261 / 890
= 261
Step2:
LCM(1, 684) = 684
GCD(1, 684) = ( 1 x 684 ) / 684
= 1 / 684
= 1
Step3:
LCM(1, 469) = 469
GCD(1, 469) = ( 1 x 469 ) / 469
= 1 / 469
= 1
So, Greatest Common Divisor of 261, 890, 684, 469 is 1
