Given numbers are 638, 782, 219, 365

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

Apply this formula for all numbers.

Step1:

LCM(638, 782) = 249458

GCD(638, 782) = ( 638 x 782 ) / 249458

= 638 / 782

= 638

Step2:

LCM(2, 219) = 438

GCD(2, 219) = ( 2 x 219 ) / 438

= 2 / 219

= 2

Step3:

LCM(1, 365) = 365

GCD(1, 365) = ( 1 x 365 ) / 365

= 1 / 365

= 1

So, Greatest Common Divisor of 638, 782, 219, 365 is 1
