GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 764) = 123004
GCD(644, 764) = ( 644 x 764 ) / 123004
= 644 / 764
= 644
Step2:
LCM(4, 741) = 2964
GCD(4, 741) = ( 4 x 741 ) / 2964
= 4 / 741
= 4
Step3:
LCM(1, 904) = 904
GCD(1, 904) = ( 1 x 904 ) / 904
= 1 / 904
= 1
So, Greatest Common Divisor of 644, 764, 741, 904 is 1
