Given numbers are 855, 830, 823, 212
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 830) = 141930
GCD(855, 830) = ( 855 x 830 ) / 141930
= 855 / 830
= 855
Step2:
LCM(5, 823) = 4115
GCD(5, 823) = ( 5 x 823 ) / 4115
= 5 / 823
= 5
Step3:
LCM(1, 212) = 212
GCD(1, 212) = ( 1 x 212 ) / 212
= 1 / 212
= 1
So, Greatest Common Divisor of 855, 830, 823, 212 is 1
