Given numbers are 638, 695, 335, 142

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

Apply this formula for all numbers.

Step1:

LCM(638, 695) = 443410

GCD(638, 695) = ( 638 x 695 ) / 443410

= 638 / 695

= 638

Step2:

LCM(1, 335) = 335

GCD(1, 335) = ( 1 x 335 ) / 335

= 1 / 335

= 1

Step3:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

So, Greatest Common Divisor of 638, 695, 335, 142 is 1
