Given numbers are 290, 155, 349, 871

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

Apply this formula for all numbers.

Step1:

LCM(290, 155) = 8990

GCD(290, 155) = ( 290 x 155 ) / 8990

= 290 / 155

= 290

Step2:

LCM(5, 349) = 1745

GCD(5, 349) = ( 5 x 349 ) / 1745

= 5 / 349

= 5

Step3:

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

= 1 / 871

= 1

So, Greatest Common Divisor of 290, 155, 349, 871 is 1
