Given numbers are 401, 478, 822, 988

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

Apply this formula for all numbers.

Step1:

LCM(401, 478) = 191678

GCD(401, 478) = ( 401 x 478 ) / 191678

= 401 / 478

= 401

Step2:

LCM(1, 822) = 822

GCD(1, 822) = ( 1 x 822 ) / 822

= 1 / 822

= 1

Step3:

LCM(1, 988) = 988

GCD(1, 988) = ( 1 x 988 ) / 988

= 1 / 988

= 1

So, Greatest Common Divisor of 401, 478, 822, 988 is 1
