Given numbers are 170, 298, 561, 804
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 298) = 25330
GCD(170, 298) = ( 170 x 298 ) / 25330
= 170 / 298
= 170
Step2:
LCM(2, 561) = 1122
GCD(2, 561) = ( 2 x 561 ) / 1122
= 2 / 561
= 2
Step3:
LCM(1, 804) = 804
GCD(1, 804) = ( 1 x 804 ) / 804
= 1 / 804
= 1
So, Greatest Common Divisor of 170, 298, 561, 804 is 1
