Given numbers are 981, 180, 513, 487
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 180) = 19620
GCD(981, 180) = ( 981 x 180 ) / 19620
= 981 / 180
= 981
Step2:
LCM(9, 513) = 513
GCD(9, 513) = ( 9 x 513 ) / 513
= 9 / 513
= 9
Step3:
LCM(9, 487) = 4383
GCD(9, 487) = ( 9 x 487 ) / 4383
= 9 / 487
= 9
So, Greatest Common Divisor of 981, 180, 513, 487 is 1
