Given numbers are 634, 834, 991, 891

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

Apply this formula for all numbers.

Step1:

LCM(634, 834) = 264378

GCD(634, 834) = ( 634 x 834 ) / 264378

= 634 / 834

= 634

Step2:

LCM(2, 991) = 1982

GCD(2, 991) = ( 2 x 991 ) / 1982

= 2 / 991

= 2

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 634, 834, 991, 891 is 1
