Given numbers are 663, 328, 272, 276
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 328) = 217464
GCD(663, 328) = ( 663 x 328 ) / 217464
= 663 / 328
= 663
Step2:
LCM(1, 272) = 272
GCD(1, 272) = ( 1 x 272 ) / 272
= 1 / 272
= 1
Step3:
LCM(1, 276) = 276
GCD(1, 276) = ( 1 x 276 ) / 276
= 1 / 276
= 1
So, Greatest Common Divisor of 663, 328, 272, 276 is 1
