Given numbers are 280, 479, 832, 830
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 479) = 134120
GCD(280, 479) = ( 280 x 479 ) / 134120
= 280 / 479
= 280
Step2:
LCM(1, 832) = 832
GCD(1, 832) = ( 1 x 832 ) / 832
= 1 / 832
= 1
Step3:
LCM(1, 830) = 830
GCD(1, 830) = ( 1 x 830 ) / 830
= 1 / 830
= 1
So, Greatest Common Divisor of 280, 479, 832, 830 is 1
