Given numbers are 409, 138, 790, 134

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

Apply this formula for all numbers.

Step1:

LCM(409, 138) = 56442

GCD(409, 138) = ( 409 x 138 ) / 56442

= 409 / 138

= 409

Step2:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

Step3:

LCM(1, 134) = 134

GCD(1, 134) = ( 1 x 134 ) / 134

= 1 / 134

= 1

So, Greatest Common Divisor of 409, 138, 790, 134 is 1
