Given numbers are 408, 418, 971, 625

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

Apply this formula for all numbers.

Step1:

LCM(408, 418) = 85272

GCD(408, 418) = ( 408 x 418 ) / 85272

= 408 / 418

= 408

Step2:

LCM(2, 971) = 1942

GCD(2, 971) = ( 2 x 971 ) / 1942

= 2 / 971

= 2

Step3:

LCM(1, 625) = 625

GCD(1, 625) = ( 1 x 625 ) / 625

= 1 / 625

= 1

So, Greatest Common Divisor of 408, 418, 971, 625 is 1
