GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 768) = 33024
GCD(172, 768) = ( 172 x 768 ) / 33024
= 172 / 768
= 172
Step2:
LCM(4, 644) = 644
GCD(4, 644) = ( 4 x 644 ) / 644
= 4 / 644
= 4
Step3:
LCM(4, 759) = 3036
GCD(4, 759) = ( 4 x 759 ) / 3036
= 4 / 759
= 4
So, Greatest Common Divisor of 172, 768, 644, 759 is 1
