Given numbers are 789, 564, 663, 400
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 564) = 148332
GCD(789, 564) = ( 789 x 564 ) / 148332
= 789 / 564
= 789
Step2:
LCM(3, 663) = 663
GCD(3, 663) = ( 3 x 663 ) / 663
= 3 / 663
= 3
Step3:
LCM(3, 400) = 1200
GCD(3, 400) = ( 3 x 400 ) / 1200
= 3 / 400
= 3
So, Greatest Common Divisor of 789, 564, 663, 400 is 1
