Given numbers are 257, 751, 557, 578

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

Apply this formula for all numbers.

Step1:

LCM(257, 751) = 193007

GCD(257, 751) = ( 257 x 751 ) / 193007

= 257 / 751

= 257

Step2:

LCM(1, 557) = 557

GCD(1, 557) = ( 1 x 557 ) / 557

= 1 / 557

= 1

Step3:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 257, 751, 557, 578 is 1
