Given numbers are 691, 163, 830, 681

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

Apply this formula for all numbers.

Step1:

LCM(691, 163) = 112633

GCD(691, 163) = ( 691 x 163 ) / 112633

= 691 / 163

= 691

Step2:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

Step3:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

So, Greatest Common Divisor of 691, 163, 830, 681 is 1
