Given numbers are 170, 405, 892, 731

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

Apply this formula for all numbers.

Step1:

LCM(170, 405) = 13770

GCD(170, 405) = ( 170 x 405 ) / 13770

= 170 / 405

= 170

Step2:

LCM(5, 892) = 4460

GCD(5, 892) = ( 5 x 892 ) / 4460

= 5 / 892

= 5

Step3:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

So, Greatest Common Divisor of 170, 405, 892, 731 is 1
