Given numbers are 618, 344, 623, 861

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

Apply this formula for all numbers.

Step1:

LCM(618, 344) = 106296

GCD(618, 344) = ( 618 x 344 ) / 106296

= 618 / 344

= 618

Step2:

LCM(2, 623) = 1246

GCD(2, 623) = ( 2 x 623 ) / 1246

= 2 / 623

= 2

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 618, 344, 623, 861 is 1
