Given numbers are 407, 131, 124, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(407, 131) = 53317
GCD(407, 131) = ( 407 x 131 ) / 53317
= 407 / 131
= 407
Step2:
LCM(1, 124) = 124
GCD(1, 124) = ( 1 x 124 ) / 124
= 1 / 124
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 407, 131, 124, 689 is 1
