Given numbers are 391, 866, 859, 862
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 866) = 338606
GCD(391, 866) = ( 391 x 866 ) / 338606
= 391 / 866
= 391
Step2:
LCM(1, 859) = 859
GCD(1, 859) = ( 1 x 859 ) / 859
= 1 / 859
= 1
Step3:
LCM(1, 862) = 862
GCD(1, 862) = ( 1 x 862 ) / 862
= 1 / 862
= 1
So, Greatest Common Divisor of 391, 866, 859, 862 is 1
