Given numbers are 217, 225, 830, 880
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 225) = 48825
GCD(217, 225) = ( 217 x 225 ) / 48825
= 217 / 225
= 217
Step2:
LCM(1, 830) = 830
GCD(1, 830) = ( 1 x 830 ) / 830
= 1 / 830
= 1
Step3:
LCM(1, 880) = 880
GCD(1, 880) = ( 1 x 880 ) / 880
= 1 / 880
= 1
So, Greatest Common Divisor of 217, 225, 830, 880 is 1
