Given numbers are 401, 802, 25, 978

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

Apply this formula for all numbers.

Step1:

LCM(401, 802) = 802

GCD(401, 802) = ( 401 x 802 ) / 802

= 401 / 802

= 401

Step2:

LCM(401, 25) = 10025

GCD(401, 25) = ( 401 x 25 ) / 10025

= 401 / 25

= 401

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 401, 802, 25, 978 is 1
