Given numbers are 638, 816, 610, 723
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 816) = 260304
GCD(638, 816) = ( 638 x 816 ) / 260304
= 638 / 816
= 638
Step2:
LCM(2, 610) = 610
GCD(2, 610) = ( 2 x 610 ) / 610
= 2 / 610
= 2
Step3:
LCM(2, 723) = 1446
GCD(2, 723) = ( 2 x 723 ) / 1446
= 2 / 723
= 2
So, Greatest Common Divisor of 638, 816, 610, 723 is 1
