Given numbers are 437, 263, 403, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(437, 263) = 114931
GCD(437, 263) = ( 437 x 263 ) / 114931
= 437 / 263
= 437
Step2:
LCM(1, 403) = 403
GCD(1, 403) = ( 1 x 403 ) / 403
= 1 / 403
= 1
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 437, 263, 403, 405 is 1
