Given numbers are 669, 342, 145, 261
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(669, 342) = 76266
GCD(669, 342) = ( 669 x 342 ) / 76266
= 669 / 342
= 669
Step2:
LCM(3, 145) = 435
GCD(3, 145) = ( 3 x 145 ) / 435
= 3 / 145
= 3
Step3:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
So, Greatest Common Divisor of 669, 342, 145, 261 is 1
