GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(636, 164) = 26076
GCD(636, 164) = ( 636 x 164 ) / 26076
= 636 / 164
= 636
Step2:
LCM(4, 290) = 580
GCD(4, 290) = ( 4 x 290 ) / 580
= 4 / 290
= 4
Step3:
LCM(2, 858) = 858
GCD(2, 858) = ( 2 x 858 ) / 858
= 2 / 858
= 2
So, Greatest Common Divisor of 636, 164, 290, 858 is 2
