Given numbers are 326, 620, 25, 661

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

Apply this formula for all numbers.

Step1:

LCM(326, 620) = 101060

GCD(326, 620) = ( 326 x 620 ) / 101060

= 326 / 620

= 326

Step2:

LCM(2, 25) = 50

GCD(2, 25) = ( 2 x 25 ) / 50

= 2 / 25

= 2

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 326, 620, 25, 661 is 1
