Given numbers are 398, 171, 507, 695

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

Apply this formula for all numbers.

Step1:

LCM(398, 171) = 68058

GCD(398, 171) = ( 398 x 171 ) / 68058

= 398 / 171

= 398

Step2:

LCM(1, 507) = 507

GCD(1, 507) = ( 1 x 507 ) / 507

= 1 / 507

= 1

Step3:

LCM(1, 695) = 695

GCD(1, 695) = ( 1 x 695 ) / 695

= 1 / 695

= 1

So, Greatest Common Divisor of 398, 171, 507, 695 is 1
