Given numbers are 211, 915, 353, 830
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(211, 915) = 193065
GCD(211, 915) = ( 211 x 915 ) / 193065
= 211 / 915
= 211
Step2:
LCM(1, 353) = 353
GCD(1, 353) = ( 1 x 353 ) / 353
= 1 / 353
= 1
Step3:
LCM(1, 830) = 830
GCD(1, 830) = ( 1 x 830 ) / 830
= 1 / 830
= 1
So, Greatest Common Divisor of 211, 915, 353, 830 is 1
