Given numbers are 663, 438, 239, 630
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 438) = 96798
GCD(663, 438) = ( 663 x 438 ) / 96798
= 663 / 438
= 663
Step2:
LCM(3, 239) = 717
GCD(3, 239) = ( 3 x 239 ) / 717
= 3 / 239
= 3
Step3:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
So, Greatest Common Divisor of 663, 438, 239, 630 is 1
