Given numbers are 172, 523, 809, 545
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 523) = 89956
GCD(172, 523) = ( 172 x 523 ) / 89956
= 172 / 523
= 172
Step2:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
Step3:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
So, Greatest Common Divisor of 172, 523, 809, 545 is 1
