Given numbers are 793, 490, 259, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(793, 490) = 388570
GCD(793, 490) = ( 793 x 490 ) / 388570
= 793 / 490
= 793
Step2:
LCM(1, 259) = 259
GCD(1, 259) = ( 1 x 259 ) / 259
= 1 / 259
= 1
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 793, 490, 259, 155 is 1
