Given numbers are 663, 279, 358, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 279) = 61659
GCD(663, 279) = ( 663 x 279 ) / 61659
= 663 / 279
= 663
Step2:
LCM(3, 358) = 1074
GCD(3, 358) = ( 3 x 358 ) / 1074
= 3 / 358
= 3
Step3:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
So, Greatest Common Divisor of 663, 279, 358, 445 is 1
