Given numbers are 644, 180, 669, 295
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 180) = 28980
GCD(644, 180) = ( 644 x 180 ) / 28980
= 644 / 180
= 644
Step2:
LCM(4, 669) = 2676
GCD(4, 669) = ( 4 x 669 ) / 2676
= 4 / 669
= 4
Step3:
LCM(1, 295) = 295
GCD(1, 295) = ( 1 x 295 ) / 295
= 1 / 295
= 1
So, Greatest Common Divisor of 644, 180, 669, 295 is 1
