Given numbers are 140, 268, 580, 858

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

Apply this formula for all numbers.

Step1:

LCM(140, 268) = 9380

GCD(140, 268) = ( 140 x 268 ) / 9380

= 140 / 268

= 140

Step2:

LCM(4, 580) = 580

GCD(4, 580) = ( 4 x 580 ) / 580

= 4 / 580

= 4

Step3:

LCM(4, 858) = 1716

GCD(4, 858) = ( 4 x 858 ) / 1716

= 4 / 858

= 4

So, Greatest Common Divisor of 140, 268, 580, 858 is 2
