Given numbers are 253, 817, 211, 485
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(253, 817) = 206701
GCD(253, 817) = ( 253 x 817 ) / 206701
= 253 / 817
= 253
Step2:
LCM(1, 211) = 211
GCD(1, 211) = ( 1 x 211 ) / 211
= 1 / 211
= 1
Step3:
LCM(1, 485) = 485
GCD(1, 485) = ( 1 x 485 ) / 485
= 1 / 485
= 1
So, Greatest Common Divisor of 253, 817, 211, 485 is 1
