Given numbers are 123, 608, 80, 813

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

Apply this formula for all numbers.

Step1:

LCM(123, 608) = 74784

GCD(123, 608) = ( 123 x 608 ) / 74784

= 123 / 608

= 123

Step2:

LCM(1, 80) = 80

GCD(1, 80) = ( 1 x 80 ) / 80

= 1 / 80

= 1

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 123, 608, 80, 813 is 1
