Given numbers are 190, 722, 638, 860

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

Apply this formula for all numbers.

Step1:

LCM(190, 722) = 3610

GCD(190, 722) = ( 190 x 722 ) / 3610

= 190 / 722

= 190

Step2:

LCM(38, 638) = 12122

GCD(38, 638) = ( 38 x 638 ) / 12122

= 38 / 638

= 38

Step3:

LCM(2, 860) = 860

GCD(2, 860) = ( 2 x 860 ) / 860

= 2 / 860

= 2

So, Greatest Common Divisor of 190, 722, 638, 860 is 2
