Given numbers are 257, 351, 417, 520
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 351) = 90207
GCD(257, 351) = ( 257 x 351 ) / 90207
= 257 / 351
= 257
Step2:
LCM(1, 417) = 417
GCD(1, 417) = ( 1 x 417 ) / 417
= 1 / 417
= 1
Step3:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
So, Greatest Common Divisor of 257, 351, 417, 520 is 1
