Given numbers are 305, 660, 484, 858
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 660) = 40260
GCD(305, 660) = ( 305 x 660 ) / 40260
= 305 / 660
= 305
Step2:
LCM(5, 484) = 2420
GCD(5, 484) = ( 5 x 484 ) / 2420
= 5 / 484
= 5
Step3:
LCM(1, 858) = 858
GCD(1, 858) = ( 1 x 858 ) / 858
= 1 / 858
= 1
So, Greatest Common Divisor of 305, 660, 484, 858 is 1
