Given numbers are 801, 153, 810, 961
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(801, 153) = 13617
GCD(801, 153) = ( 801 x 153 ) / 13617
= 801 / 153
= 801
Step2:
LCM(9, 810) = 810
GCD(9, 810) = ( 9 x 810 ) / 810
= 9 / 810
= 9
Step3:
LCM(9, 961) = 8649
GCD(9, 961) = ( 9 x 961 ) / 8649
= 9 / 961
= 9
So, Greatest Common Divisor of 801, 153, 810, 961 is 1
