Given numbers are 172, 205, 409, 279
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 205) = 35260
GCD(172, 205) = ( 172 x 205 ) / 35260
= 172 / 205
= 172
Step2:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
Step3:
LCM(1, 279) = 279
GCD(1, 279) = ( 1 x 279 ) / 279
= 1 / 279
= 1
So, Greatest Common Divisor of 172, 205, 409, 279 is 1
