Given numbers are 981, 436, 280, 443

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

Apply this formula for all numbers.

Step1:

LCM(981, 436) = 3924

GCD(981, 436) = ( 981 x 436 ) / 3924

= 981 / 436

= 981

Step2:

LCM(109, 280) = 30520

GCD(109, 280) = ( 109 x 280 ) / 30520

= 109 / 280

= 109

Step3:

LCM(1, 443) = 443

GCD(1, 443) = ( 1 x 443 ) / 443

= 1 / 443

= 1

So, Greatest Common Divisor of 981, 436, 280, 443 is 1
