Given numbers are 164, 790, 121, 769
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(164, 790) = 64780
GCD(164, 790) = ( 164 x 790 ) / 64780
= 164 / 790
= 164
Step2:
LCM(2, 121) = 242
GCD(2, 121) = ( 2 x 121 ) / 242
= 2 / 121
= 2
Step3:
LCM(1, 769) = 769
GCD(1, 769) = ( 1 x 769 ) / 769
= 1 / 769
= 1
So, Greatest Common Divisor of 164, 790, 121, 769 is 1
