GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 105) = 23205
GCD(663, 105) = ( 663 x 105 ) / 23205
= 663 / 105
= 663
Step2:
LCM(3, 806) = 2418
GCD(3, 806) = ( 3 x 806 ) / 2418
= 3 / 806
= 3
Step3:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
So, Greatest Common Divisor of 663, 105, 806, 530 is 1
