Given numbers are 860, 188, 858, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(860, 188) = 40420
GCD(860, 188) = ( 860 x 188 ) / 40420
= 860 / 188
= 860
Step2:
LCM(4, 858) = 1716
GCD(4, 858) = ( 4 x 858 ) / 1716
= 4 / 858
= 4
Step3:
LCM(2, 405) = 810
GCD(2, 405) = ( 2 x 405 ) / 810
= 2 / 405
= 2
So, Greatest Common Divisor of 860, 188, 858, 405 is 1
