Given numbers are 663, 505, 39, 844

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

Apply this formula for all numbers.

Step1:

LCM(663, 505) = 334815

GCD(663, 505) = ( 663 x 505 ) / 334815

= 663 / 505

= 663

Step2:

LCM(1, 39) = 39

GCD(1, 39) = ( 1 x 39 ) / 39

= 1 / 39

= 1

Step3:

LCM(1, 844) = 844

GCD(1, 844) = ( 1 x 844 ) / 844

= 1 / 844

= 1

So, Greatest Common Divisor of 663, 505, 39, 844 is 1
