Given numbers are 981, 804, 647, 297

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

Apply this formula for all numbers.

Step1:

LCM(981, 804) = 262908

GCD(981, 804) = ( 981 x 804 ) / 262908

= 981 / 804

= 981

Step2:

LCM(3, 647) = 1941

GCD(3, 647) = ( 3 x 647 ) / 1941

= 3 / 647

= 3

Step3:

LCM(1, 297) = 297

GCD(1, 297) = ( 1 x 297 ) / 297

= 1 / 297

= 1

So, Greatest Common Divisor of 981, 804, 647, 297 is 1
