Given numbers are 861, 803, 655, 695

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

Apply this formula for all numbers.

Step1:

LCM(861, 803) = 691383

GCD(861, 803) = ( 861 x 803 ) / 691383

= 861 / 803

= 861

Step2:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

Step3:

LCM(1, 695) = 695

GCD(1, 695) = ( 1 x 695 ) / 695

= 1 / 695

= 1

So, Greatest Common Divisor of 861, 803, 655, 695 is 1
