Given numbers are 811, 830, 797, 987

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

Apply this formula for all numbers.

Step1:

LCM(811, 830) = 673130

GCD(811, 830) = ( 811 x 830 ) / 673130

= 811 / 830

= 811

Step2:

LCM(1, 797) = 797

GCD(1, 797) = ( 1 x 797 ) / 797

= 1 / 797

= 1

Step3:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

So, Greatest Common Divisor of 811, 830, 797, 987 is 1
