Given numbers are 855, 885, 173, 102
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 885) = 50445
GCD(855, 885) = ( 855 x 885 ) / 50445
= 855 / 885
= 855
Step2:
LCM(15, 173) = 2595
GCD(15, 173) = ( 15 x 173 ) / 2595
= 15 / 173
= 15
Step3:
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
= 1 / 102
= 1
So, Greatest Common Divisor of 855, 885, 173, 102 is 1
