Given numbers are 405, 816, 152, 682
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 816) = 110160
GCD(405, 816) = ( 405 x 816 ) / 110160
= 405 / 816
= 405
Step2:
LCM(3, 152) = 456
GCD(3, 152) = ( 3 x 152 ) / 456
= 3 / 152
= 3
Step3:
LCM(1, 682) = 682
GCD(1, 682) = ( 1 x 682 ) / 682
= 1 / 682
= 1
So, Greatest Common Divisor of 405, 816, 152, 682 is 1
