Given numbers are 855, 651, 842, 808
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 651) = 185535
GCD(855, 651) = ( 855 x 651 ) / 185535
= 855 / 651
= 855
Step2:
LCM(3, 842) = 2526
GCD(3, 842) = ( 3 x 842 ) / 2526
= 3 / 842
= 3
Step3:
LCM(1, 808) = 808
GCD(1, 808) = ( 1 x 808 ) / 808
= 1 / 808
= 1
So, Greatest Common Divisor of 855, 651, 842, 808 is 1
