Given numbers are 357, 231, 491, 404
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(357, 231) = 3927
GCD(357, 231) = ( 357 x 231 ) / 3927
= 357 / 231
= 357
Step2:
LCM(21, 491) = 10311
GCD(21, 491) = ( 21 x 491 ) / 10311
= 21 / 491
= 21
Step3:
LCM(1, 404) = 404
GCD(1, 404) = ( 1 x 404 ) / 404
= 1 / 404
= 1
So, Greatest Common Divisor of 357, 231, 491, 404 is 1
