GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 992) = 659680
GCD(665, 992) = ( 665 x 992 ) / 659680
= 665 / 992
= 665
Step2:
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
= 1 / 278
= 1
Step3:
LCM(1, 869) = 869
GCD(1, 869) = ( 1 x 869 ) / 869
= 1 / 869
= 1
So, Greatest Common Divisor of 665, 992, 278, 869 is 1
