Given numbers are 801, 747, 855, 421

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

Apply this formula for all numbers.

Step1:

LCM(801, 747) = 66483

GCD(801, 747) = ( 801 x 747 ) / 66483

= 801 / 747

= 801

Step2:

LCM(9, 855) = 855

GCD(9, 855) = ( 9 x 855 ) / 855

= 9 / 855

= 9

Step3:

LCM(9, 421) = 3789

GCD(9, 421) = ( 9 x 421 ) / 3789

= 9 / 421

= 9

So, Greatest Common Divisor of 801, 747, 855, 421 is 1
