Given numbers are 206, 326, 505, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(206, 326) = 33578
GCD(206, 326) = ( 206 x 326 ) / 33578
= 206 / 326
= 206
Step2:
LCM(2, 505) = 1010
GCD(2, 505) = ( 2 x 505 ) / 1010
= 2 / 505
= 2
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 206, 326, 505, 621 is 1
