Given numbers are 663, 700, 172, 938
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 700) = 464100
GCD(663, 700) = ( 663 x 700 ) / 464100
= 663 / 700
= 663
Step2:
LCM(1, 172) = 172
GCD(1, 172) = ( 1 x 172 ) / 172
= 1 / 172
= 1
Step3:
LCM(1, 938) = 938
GCD(1, 938) = ( 1 x 938 ) / 938
= 1 / 938
= 1
So, Greatest Common Divisor of 663, 700, 172, 938 is 1
