Given numbers are 663, 855, 451, 669
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 855) = 188955
GCD(663, 855) = ( 663 x 855 ) / 188955
= 663 / 855
= 663
Step2:
LCM(3, 451) = 1353
GCD(3, 451) = ( 3 x 451 ) / 1353
= 3 / 451
= 3
Step3:
LCM(1, 669) = 669
GCD(1, 669) = ( 1 x 669 ) / 669
= 1 / 669
= 1
So, Greatest Common Divisor of 663, 855, 451, 669 is 1
