Given numbers are 395, 145, 961, 970

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

Apply this formula for all numbers.

Step1:

LCM(395, 145) = 11455

GCD(395, 145) = ( 395 x 145 ) / 11455

= 395 / 145

= 395

Step2:

LCM(5, 961) = 4805

GCD(5, 961) = ( 5 x 961 ) / 4805

= 5 / 961

= 5

Step3:

LCM(1, 970) = 970

GCD(1, 970) = ( 1 x 970 ) / 970

= 1 / 970

= 1

So, Greatest Common Divisor of 395, 145, 961, 970 is 1
