Given numbers are 258, 369, 557, 855

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

Apply this formula for all numbers.

Step1:

LCM(258, 369) = 31734

GCD(258, 369) = ( 258 x 369 ) / 31734

= 258 / 369

= 258

Step2:

LCM(3, 557) = 1671

GCD(3, 557) = ( 3 x 557 ) / 1671

= 3 / 557

= 3

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 258, 369, 557, 855 is 1
