Given numbers are 803, 357, 243, 421
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(803, 357) = 286671
GCD(803, 357) = ( 803 x 357 ) / 286671
= 803 / 357
= 803
Step2:
LCM(1, 243) = 243
GCD(1, 243) = ( 1 x 243 ) / 243
= 1 / 243
= 1
Step3:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
So, Greatest Common Divisor of 803, 357, 243, 421 is 1
