Given numbers are 841, 257, 140

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

Apply this formula for all numbers.

Step1:

LCM(841, 257) = 216137

GCD(841, 257) = ( 841 x 257 ) / 216137

= 841 / 257

= 841

Step2:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

So, Greatest Common Divisor of 841, 257, 140 is 1
