Given numbers are 478, 258, 155, 525

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

Apply this formula for all numbers.

Step1:

LCM(478, 258) = 61662

GCD(478, 258) = ( 478 x 258 ) / 61662

= 478 / 258

= 478

Step2:

LCM(2, 155) = 310

GCD(2, 155) = ( 2 x 155 ) / 310

= 2 / 155

= 2

Step3:

LCM(1, 525) = 525

GCD(1, 525) = ( 1 x 525 ) / 525

= 1 / 525

= 1

So, Greatest Common Divisor of 478, 258, 155, 525 is 1
