Given numbers are 981, 729, 634, 844

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

Apply this formula for all numbers.

Step1:

LCM(981, 729) = 79461

GCD(981, 729) = ( 981 x 729 ) / 79461

= 981 / 729

= 981

Step2:

LCM(9, 634) = 5706

GCD(9, 634) = ( 9 x 634 ) / 5706

= 9 / 634

= 9

Step3:

LCM(1, 844) = 844

GCD(1, 844) = ( 1 x 844 ) / 844

= 1 / 844

= 1

So, Greatest Common Divisor of 981, 729, 634, 844 is 1
