Given numbers are 864, 752, 809, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(864, 752) = 40608
GCD(864, 752) = ( 864 x 752 ) / 40608
= 864 / 752
= 864
Step2:
LCM(16, 809) = 12944
GCD(16, 809) = ( 16 x 809 ) / 12944
= 16 / 809
= 16
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 864, 752, 809, 644 is 1
