Given numbers are 671, 980, 81, 911
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(671, 980) = 657580
GCD(671, 980) = ( 671 x 980 ) / 657580
= 671 / 980
= 671
Step2:
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
= 1 / 81
= 1
Step3:
LCM(1, 911) = 911
GCD(1, 911) = ( 1 x 911 ) / 911
= 1 / 911
= 1
So, Greatest Common Divisor of 671, 980, 81, 911 is 1
