Given numbers are 460, 605, 816, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(460, 605) = 55660
GCD(460, 605) = ( 460 x 605 ) / 55660
= 460 / 605
= 460
Step2:
LCM(5, 816) = 4080
GCD(5, 816) = ( 5 x 816 ) / 4080
= 5 / 816
= 5
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 460, 605, 816, 644 is 1
