Given numbers are 272, 818, 603, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(272, 818) = 111248
GCD(272, 818) = ( 272 x 818 ) / 111248
= 272 / 818
= 272
Step2:
LCM(2, 603) = 1206
GCD(2, 603) = ( 2 x 603 ) / 1206
= 2 / 603
= 2
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 272, 818, 603, 257 is 1
