Given numbers are 678, 140, 442, 193

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

Apply this formula for all numbers.

Step1:

LCM(678, 140) = 47460

GCD(678, 140) = ( 678 x 140 ) / 47460

= 678 / 140

= 678

Step2:

LCM(2, 442) = 442

GCD(2, 442) = ( 2 x 442 ) / 442

= 2 / 442

= 2

Step3:

LCM(2, 193) = 386

GCD(2, 193) = ( 2 x 193 ) / 386

= 2 / 193

= 2

So, Greatest Common Divisor of 678, 140, 442, 193 is 1
