Given numbers are 390, 663, 69, 436

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

Apply this formula for all numbers.

Step1:

LCM(390, 663) = 6630

GCD(390, 663) = ( 390 x 663 ) / 6630

= 390 / 663

= 390

Step2:

LCM(39, 69) = 897

GCD(39, 69) = ( 39 x 69 ) / 897

= 39 / 69

= 39

Step3:

LCM(3, 436) = 1308

GCD(3, 436) = ( 3 x 436 ) / 1308

= 3 / 436

= 3

So, Greatest Common Divisor of 390, 663, 69, 436 is 1
