Given numbers are 638, 930, 194, 653

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

Apply this formula for all numbers.

Step1:

LCM(638, 930) = 296670

GCD(638, 930) = ( 638 x 930 ) / 296670

= 638 / 930

= 638

Step2:

LCM(2, 194) = 194

GCD(2, 194) = ( 2 x 194 ) / 194

= 2 / 194

= 2

Step3:

LCM(2, 653) = 1306

GCD(2, 653) = ( 2 x 653 ) / 1306

= 2 / 653

= 2

So, Greatest Common Divisor of 638, 930, 194, 653 is 1
