Given numbers are 166, 838, 258, 487

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

Apply this formula for all numbers.

Step1:

LCM(166, 838) = 69554

GCD(166, 838) = ( 166 x 838 ) / 69554

= 166 / 838

= 166

Step2:

LCM(2, 258) = 258

GCD(2, 258) = ( 2 x 258 ) / 258

= 2 / 258

= 2

Step3:

LCM(2, 487) = 974

GCD(2, 487) = ( 2 x 487 ) / 974

= 2 / 487

= 2

So, Greatest Common Divisor of 166, 838, 258, 487 is 1
