Given numbers are 409, 918, 430, 705

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(409, 918) = 375462

GCD(409, 918) = ( 409 x 918 ) / 375462

= 409 / 918

= 409

Step2:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

Step3:

LCM(1, 705) = 705

GCD(1, 705) = ( 1 x 705 ) / 705

= 1 / 705

= 1

So, Greatest Common Divisor of 409, 918, 430, 705 is 1
