Given numbers are 158, 705, 421, 585
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(158, 705) = 111390
GCD(158, 705) = ( 158 x 705 ) / 111390
= 158 / 705
= 158
Step2:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
Step3:
LCM(1, 585) = 585
GCD(1, 585) = ( 1 x 585 ) / 585
= 1 / 585
= 1
So, Greatest Common Divisor of 158, 705, 421, 585 is 1
