Given numbers are 427, 257, 422, 472
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(427, 257) = 109739
GCD(427, 257) = ( 427 x 257 ) / 109739
= 427 / 257
= 427
Step2:
LCM(1, 422) = 422
GCD(1, 422) = ( 1 x 422 ) / 422
= 1 / 422
= 1
Step3:
LCM(1, 472) = 472
GCD(1, 472) = ( 1 x 472 ) / 472
= 1 / 472
= 1
So, Greatest Common Divisor of 427, 257, 422, 472 is 1
