Given numbers are 212, 687, 930, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(212, 687) = 145644
GCD(212, 687) = ( 212 x 687 ) / 145644
= 212 / 687
= 212
Step2:
LCM(1, 930) = 930
GCD(1, 930) = ( 1 x 930 ) / 930
= 1 / 930
= 1
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 212, 687, 930, 221 is 1
