Given numbers are 659, 623, 86, 981

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

Apply this formula for all numbers.

Step1:

LCM(659, 623) = 410557

GCD(659, 623) = ( 659 x 623 ) / 410557

= 659 / 623

= 659

Step2:

LCM(1, 86) = 86

GCD(1, 86) = ( 1 x 86 ) / 86

= 1 / 86

= 1

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 659, 623, 86, 981 is 1
