Given numbers are 681, 446, 545, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(681, 446) = 303726
GCD(681, 446) = ( 681 x 446 ) / 303726
= 681 / 446
= 681
Step2:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 681, 446, 545, 690 is 1
