Given numbers are 812, 278, 401, 981
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(812, 278) = 112868
GCD(812, 278) = ( 812 x 278 ) / 112868
= 812 / 278
= 812
Step2:
LCM(2, 401) = 802
GCD(2, 401) = ( 2 x 401 ) / 802
= 2 / 401
= 2
Step3:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
So, Greatest Common Divisor of 812, 278, 401, 981 is 1
