Given numbers are 221, 661, 623, 928
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 661) = 146081
GCD(221, 661) = ( 221 x 661 ) / 146081
= 221 / 661
= 221
Step2:
LCM(1, 623) = 623
GCD(1, 623) = ( 1 x 623 ) / 623
= 1 / 623
= 1
Step3:
LCM(1, 928) = 928
GCD(1, 928) = ( 1 x 928 ) / 928
= 1 / 928
= 1
So, Greatest Common Divisor of 221, 661, 623, 928 is 1
