Given numbers are 893, 280, 669, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(893, 280) = 250040
GCD(893, 280) = ( 893 x 280 ) / 250040
= 893 / 280
= 893
Step2:
LCM(1, 669) = 669
GCD(1, 669) = ( 1 x 669 ) / 669
= 1 / 669
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 893, 280, 669, 689 is 1
