Given numbers are 638, 802, 740, 393

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

Apply this formula for all numbers.

Step1:

LCM(638, 802) = 255838

GCD(638, 802) = ( 638 x 802 ) / 255838

= 638 / 802

= 638

Step2:

LCM(2, 740) = 740

GCD(2, 740) = ( 2 x 740 ) / 740

= 2 / 740

= 2

Step3:

LCM(2, 393) = 786

GCD(2, 393) = ( 2 x 393 ) / 786

= 2 / 393

= 2

So, Greatest Common Divisor of 638, 802, 740, 393 is 1
