Given numbers are 217, 849, 821, 273
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 849) = 184233
GCD(217, 849) = ( 217 x 849 ) / 184233
= 217 / 849
= 217
Step2:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
Step3:
LCM(1, 273) = 273
GCD(1, 273) = ( 1 x 273 ) / 273
= 1 / 273
= 1
So, Greatest Common Divisor of 217, 849, 821, 273 is 1
