Given numbers are 690, 260, 409
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 260) = 17940
GCD(690, 260) = ( 690 x 260 ) / 17940
= 690 / 260
= 690
Step2:
LCM(10, 409) = 4090
GCD(10, 409) = ( 10 x 409 ) / 4090
= 10 / 409
= 10
So, Greatest Common Divisor of 690, 260, 409 is 1
