Given numbers are 258, 117, 175, 620

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

Apply this formula for all numbers.

Step1:

LCM(258, 117) = 10062

GCD(258, 117) = ( 258 x 117 ) / 10062

= 258 / 117

= 258

Step2:

LCM(3, 175) = 525

GCD(3, 175) = ( 3 x 175 ) / 525

= 3 / 175

= 3

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 258, 117, 175, 620 is 1
