Given numbers are 123, 297, 542, 786

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

Apply this formula for all numbers.

Step1:

LCM(123, 297) = 12177

GCD(123, 297) = ( 123 x 297 ) / 12177

= 123 / 297

= 123

Step2:

LCM(3, 542) = 1626

GCD(3, 542) = ( 3 x 542 ) / 1626

= 3 / 542

= 3

Step3:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

So, Greatest Common Divisor of 123, 297, 542, 786 is 1
