GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 824) = 180456
GCD(438, 824) = ( 438 x 824 ) / 180456
= 438 / 824
= 438
Step2:
LCM(2, 660) = 660
GCD(2, 660) = ( 2 x 660 ) / 660
= 2 / 660
= 2
Step3:
LCM(2, 663) = 1326
GCD(2, 663) = ( 2 x 663 ) / 1326
= 2 / 663
= 2
So, Greatest Common Divisor of 438, 824, 660, 663 is 1
