Given numbers are 861, 255, 135, 126

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

Apply this formula for all numbers.

Step1:

LCM(861, 255) = 73185

GCD(861, 255) = ( 861 x 255 ) / 73185

= 861 / 255

= 861

Step2:

LCM(3, 135) = 135

GCD(3, 135) = ( 3 x 135 ) / 135

= 3 / 135

= 3

Step3:

LCM(3, 126) = 126

GCD(3, 126) = ( 3 x 126 ) / 126

= 3 / 126

= 3

So, Greatest Common Divisor of 861, 255, 135, 126 is 3
