GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(605, 858) = 47190
GCD(605, 858) = ( 605 x 858 ) / 47190
= 605 / 858
= 605
Step2:
LCM(11, 857) = 9427
GCD(11, 857) = ( 11 x 857 ) / 9427
= 11 / 857
= 11
Step3:
LCM(1, 288) = 288
GCD(1, 288) = ( 1 x 288 ) / 288
= 1 / 288
= 1
So, Greatest Common Divisor of 605, 858, 857, 288 is 1
