Given numbers are 690, 665, 384, 560
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 665) = 91770
GCD(690, 665) = ( 690 x 665 ) / 91770
= 690 / 665
= 690
Step2:
LCM(5, 384) = 1920
GCD(5, 384) = ( 5 x 384 ) / 1920
= 5 / 384
= 5
Step3:
LCM(1, 560) = 560
GCD(1, 560) = ( 1 x 560 ) / 560
= 1 / 560
= 1
So, Greatest Common Divisor of 690, 665, 384, 560 is 1
