Given numbers are 813, 849, 692, 661

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

Apply this formula for all numbers.

Step1:

LCM(813, 849) = 230079

GCD(813, 849) = ( 813 x 849 ) / 230079

= 813 / 849

= 813

Step2:

LCM(3, 692) = 2076

GCD(3, 692) = ( 3 x 692 ) / 2076

= 3 / 692

= 3

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 813, 849, 692, 661 is 1
