Given numbers are 699, 720, 676, 285
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(699, 720) = 167760
GCD(699, 720) = ( 699 x 720 ) / 167760
= 699 / 720
= 699
Step2:
LCM(3, 676) = 2028
GCD(3, 676) = ( 3 x 676 ) / 2028
= 3 / 676
= 3
Step3:
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
= 1 / 285
= 1
So, Greatest Common Divisor of 699, 720, 676, 285 is 1
