Given numbers are 550, 169, 768, 441
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(550, 169) = 92950
GCD(550, 169) = ( 550 x 169 ) / 92950
= 550 / 169
= 550
Step2:
LCM(1, 768) = 768
GCD(1, 768) = ( 1 x 768 ) / 768
= 1 / 768
= 1
Step3:
LCM(1, 441) = 441
GCD(1, 441) = ( 1 x 441 ) / 441
= 1 / 441
= 1
So, Greatest Common Divisor of 550, 169, 768, 441 is 1
