Given numbers are 989, 731, 436, 991

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

Apply this formula for all numbers.

Step1:

LCM(989, 731) = 16813

GCD(989, 731) = ( 989 x 731 ) / 16813

= 989 / 731

= 989

Step2:

LCM(43, 436) = 18748

GCD(43, 436) = ( 43 x 436 ) / 18748

= 43 / 436

= 43

Step3:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

So, Greatest Common Divisor of 989, 731, 436, 991 is 1
