Given numbers are 998, 255, 169, 756
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(998, 255) = 254490
GCD(998, 255) = ( 998 x 255 ) / 254490
= 998 / 255
= 998
Step2:
LCM(1, 169) = 169
GCD(1, 169) = ( 1 x 169 ) / 169
= 1 / 169
= 1
Step3:
LCM(1, 756) = 756
GCD(1, 756) = ( 1 x 756 ) / 756
= 1 / 756
= 1
So, Greatest Common Divisor of 998, 255, 169, 756 is 1
