Given numbers are 663, 400, 847, 631
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 400) = 265200
GCD(663, 400) = ( 663 x 400 ) / 265200
= 663 / 400
= 663
Step2:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
Step3:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
So, Greatest Common Divisor of 663, 400, 847, 631 is 1
