Given numbers are 644, 543, 649, 401
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 543) = 349692
GCD(644, 543) = ( 644 x 543 ) / 349692
= 644 / 543
= 644
Step2:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
Step3:
LCM(1, 401) = 401
GCD(1, 401) = ( 1 x 401 ) / 401
= 1 / 401
= 1
So, Greatest Common Divisor of 644, 543, 649, 401 is 1
