Given numbers are 658, 731, 869, 720
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 731) = 480998
GCD(658, 731) = ( 658 x 731 ) / 480998
= 658 / 731
= 658
Step2:
LCM(1, 869) = 869
GCD(1, 869) = ( 1 x 869 ) / 869
= 1 / 869
= 1
Step3:
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
= 1 / 720
= 1
So, Greatest Common Divisor of 658, 731, 869, 720 is 1
