Given numbers are 623, 427, 732, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(623, 427) = 38003
GCD(623, 427) = ( 623 x 427 ) / 38003
= 623 / 427
= 623
Step2:
LCM(7, 732) = 5124
GCD(7, 732) = ( 7 x 732 ) / 5124
= 7 / 732
= 7
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 623, 427, 732, 221 is 1
