Given numbers are 812, 342, 892, 991

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

Apply this formula for all numbers.

Step1:

LCM(812, 342) = 138852

GCD(812, 342) = ( 812 x 342 ) / 138852

= 812 / 342

= 812

Step2:

LCM(2, 892) = 892

GCD(2, 892) = ( 2 x 892 ) / 892

= 2 / 892

= 2

Step3:

LCM(2, 991) = 1982

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

= 2 / 991

= 2

So, Greatest Common Divisor of 812, 342, 892, 991 is 1
