GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(165, 446) = 73590
GCD(165, 446) = ( 165 x 446 ) / 73590
= 165 / 446
= 165
Step2:
LCM(1, 795) = 795
GCD(1, 795) = ( 1 x 795 ) / 795
= 1 / 795
= 1
Step3:
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
= 1 / 720
= 1
So, Greatest Common Divisor of 165, 446, 795, 720 is 1
