Given numbers are 858, 780, 266, 903
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 780) = 8580
GCD(858, 780) = ( 858 x 780 ) / 8580
= 858 / 780
= 858
Step2:
LCM(78, 266) = 10374
GCD(78, 266) = ( 78 x 266 ) / 10374
= 78 / 266
= 78
Step3:
LCM(2, 903) = 1806
GCD(2, 903) = ( 2 x 903 ) / 1806
= 2 / 903
= 2
So, Greatest Common Divisor of 858, 780, 266, 903 is 1
