Given numbers are 679, 665, 239, 731
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(679, 665) = 64505
GCD(679, 665) = ( 679 x 665 ) / 64505
= 679 / 665
= 679
Step2:
LCM(7, 239) = 1673
GCD(7, 239) = ( 7 x 239 ) / 1673
= 7 / 239
= 7
Step3:
LCM(1, 731) = 731
GCD(1, 731) = ( 1 x 731 ) / 731
= 1 / 731
= 1
So, Greatest Common Divisor of 679, 665, 239, 731 is 1
