Given numbers are 816, 245, 649, 706
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(816, 245) = 199920
GCD(816, 245) = ( 816 x 245 ) / 199920
= 816 / 245
= 816
Step2:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
Step3:
LCM(1, 706) = 706
GCD(1, 706) = ( 1 x 706 ) / 706
= 1 / 706
= 1
So, Greatest Common Divisor of 816, 245, 649, 706 is 1
