Given numbers are 981, 918, 743, 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, 918) = 100062

GCD(981, 918) = ( 981 x 918 ) / 100062

= 981 / 918

= 981

Step2:

LCM(9, 743) = 6687

GCD(9, 743) = ( 9 x 743 ) / 6687

= 9 / 743

= 9

Step3:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

So, Greatest Common Divisor of 981, 918, 743, 487 is 1
