Given numbers are 172, 794, 796, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 794) = 68284
GCD(172, 794) = ( 172 x 794 ) / 68284
= 172 / 794
= 172
Step2:
LCM(2, 796) = 796
GCD(2, 796) = ( 2 x 796 ) / 796
= 2 / 796
= 2
Step3:
LCM(2, 815) = 1630
GCD(2, 815) = ( 2 x 815 ) / 1630
= 2 / 815
= 2
So, Greatest Common Divisor of 172, 794, 796, 815 is 1
