Given numbers are 387, 243, 258, 758

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

Apply this formula for all numbers.

Step1:

LCM(387, 243) = 10449

GCD(387, 243) = ( 387 x 243 ) / 10449

= 387 / 243

= 387

Step2:

LCM(9, 258) = 774

GCD(9, 258) = ( 9 x 258 ) / 774

= 9 / 258

= 9

Step3:

LCM(3, 758) = 2274

GCD(3, 758) = ( 3 x 758 ) / 2274

= 3 / 758

= 3

So, Greatest Common Divisor of 387, 243, 258, 758 is 1
