Given numbers are 398, 257, 765, 650
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 257) = 102286
GCD(398, 257) = ( 398 x 257 ) / 102286
= 398 / 257
= 398
Step2:
LCM(1, 765) = 765
GCD(1, 765) = ( 1 x 765 ) / 765
= 1 / 765
= 1
Step3:
LCM(1, 650) = 650
GCD(1, 650) = ( 1 x 650 ) / 650
= 1 / 650
= 1
So, Greatest Common Divisor of 398, 257, 765, 650 is 1
