Given numbers are 419, 145, 862, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(419, 145) = 60755
GCD(419, 145) = ( 419 x 145 ) / 60755
= 419 / 145
= 419
Step2:
LCM(1, 862) = 862
GCD(1, 862) = ( 1 x 862 ) / 862
= 1 / 862
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 419, 145, 862, 689 is 1
