Given numbers are 406, 178, 340, 725
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 178) = 36134
GCD(406, 178) = ( 406 x 178 ) / 36134
= 406 / 178
= 406
Step2:
LCM(2, 340) = 340
GCD(2, 340) = ( 2 x 340 ) / 340
= 2 / 340
= 2
Step3:
LCM(2, 725) = 1450
GCD(2, 725) = ( 2 x 725 ) / 1450
= 2 / 725
= 2
So, Greatest Common Divisor of 406, 178, 340, 725 is 1
