Given numbers are 689, 645, 204, 590
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 645) = 444405
GCD(689, 645) = ( 689 x 645 ) / 444405
= 689 / 645
= 689
Step2:
LCM(1, 204) = 204
GCD(1, 204) = ( 1 x 204 ) / 204
= 1 / 204
= 1
Step3:
LCM(1, 590) = 590
GCD(1, 590) = ( 1 x 590 ) / 590
= 1 / 590
= 1
So, Greatest Common Divisor of 689, 645, 204, 590 is 1
