Given numbers are 991, 807, 79, 840

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

Apply this formula for all numbers.

Step1:

LCM(991, 807) = 799737

GCD(991, 807) = ( 991 x 807 ) / 799737

= 991 / 807

= 991

Step2:

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

= 1 / 79

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 991, 807, 79, 840 is 1
