Given numbers are 190, 348, 628, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(190, 348) = 33060
GCD(190, 348) = ( 190 x 348 ) / 33060
= 190 / 348
= 190
Step2:
LCM(2, 628) = 628
GCD(2, 628) = ( 2 x 628 ) / 628
= 2 / 628
= 2
Step3:
LCM(2, 257) = 514
GCD(2, 257) = ( 2 x 257 ) / 514
= 2 / 257
= 2
So, Greatest Common Divisor of 190, 348, 628, 257 is 1
