Given numbers are 297, 147, 140, 861

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

Apply this formula for all numbers.

Step1:

LCM(297, 147) = 14553

GCD(297, 147) = ( 297 x 147 ) / 14553

= 297 / 147

= 297

Step2:

LCM(3, 140) = 420

GCD(3, 140) = ( 3 x 140 ) / 420

= 3 / 140

= 3

Step3:

LCM(1, 861) = 861

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

= 1 / 861

= 1

So, Greatest Common Divisor of 297, 147, 140, 861 is 1
