Given numbers are 981, 603, 803, 513

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(981, 603) = 65727

GCD(981, 603) = ( 981 x 603 ) / 65727

= 981 / 603

= 981

Step2:

LCM(9, 803) = 7227

GCD(9, 803) = ( 9 x 803 ) / 7227

= 9 / 803

= 9

Step3:

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

= 1 / 513

= 1

So, Greatest Common Divisor of 981, 603, 803, 513 is 1
