Given numbers are 142, 730, 938, 255

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

Apply this formula for all numbers.

Step1:

LCM(142, 730) = 51830

GCD(142, 730) = ( 142 x 730 ) / 51830

= 142 / 730

= 142

Step2:

LCM(2, 938) = 938

GCD(2, 938) = ( 2 x 938 ) / 938

= 2 / 938

= 2

Step3:

LCM(2, 255) = 510

GCD(2, 255) = ( 2 x 255 ) / 510

= 2 / 255

= 2

So, Greatest Common Divisor of 142, 730, 938, 255 is 1
