Given numbers are 157, 302, 123, 810

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

Apply this formula for all numbers.

Step1:

LCM(157, 302) = 47414

GCD(157, 302) = ( 157 x 302 ) / 47414

= 157 / 302

= 157

Step2:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 157, 302, 123, 810 is 1
