Given numbers are 213, 579, 646, 361
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 579) = 41109
GCD(213, 579) = ( 213 x 579 ) / 41109
= 213 / 579
= 213
Step2:
LCM(3, 646) = 1938
GCD(3, 646) = ( 3 x 646 ) / 1938
= 3 / 646
= 3
Step3:
LCM(1, 361) = 361
GCD(1, 361) = ( 1 x 361 ) / 361
= 1 / 361
= 1
So, Greatest Common Divisor of 213, 579, 646, 361 is 1
