Given numbers are 858, 930, 449, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 930) = 132990
GCD(858, 930) = ( 858 x 930 ) / 132990
= 858 / 930
= 858
Step2:
LCM(6, 449) = 2694
GCD(6, 449) = ( 6 x 449 ) / 2694
= 6 / 449
= 6
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 858, 930, 449, 155 is 1
