GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 706) = 60716
GCD(172, 706) = ( 172 x 706 ) / 60716
= 172 / 706
= 172
Step2:
LCM(2, 943) = 1886
GCD(2, 943) = ( 2 x 943 ) / 1886
= 2 / 943
= 2
Step3:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
So, Greatest Common Divisor of 172, 706, 943, 915 is 1
