Given numbers are 170, 391, 731, 825
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 391) = 3910
GCD(170, 391) = ( 170 x 391 ) / 3910
= 170 / 391
= 170
Step2:
LCM(17, 731) = 731
GCD(17, 731) = ( 17 x 731 ) / 731
= 17 / 731
= 17
Step3:
LCM(17, 825) = 14025
GCD(17, 825) = ( 17 x 825 ) / 14025
= 17 / 825
= 17
So, Greatest Common Divisor of 170, 391, 731, 825 is 1
