Given numbers are 190, 694, 655, 639

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

Apply this formula for all numbers.

Step1:

LCM(190, 694) = 65930

GCD(190, 694) = ( 190 x 694 ) / 65930

= 190 / 694

= 190

Step2:

LCM(2, 655) = 1310

GCD(2, 655) = ( 2 x 655 ) / 1310

= 2 / 655

= 2

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 190, 694, 655, 639 is 1
