Given numbers are 160, 684, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(160, 684) = 27360
GCD(160, 684) = ( 160 x 684 ) / 27360
= 160 / 684
= 160
Step2:
LCM(4, 405) = 1620
GCD(4, 405) = ( 4 x 405 ) / 1620
= 4 / 405
= 4
So, Greatest Common Divisor of 160, 684, 405 is 1
