GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 772) = 660060
GCD(855, 772) = ( 855 x 772 ) / 660060
= 855 / 772
= 855
Step2:
LCM(1, 289) = 289
GCD(1, 289) = ( 1 x 289 ) / 289
= 1 / 289
= 1
Step3:
LCM(1, 246) = 246
GCD(1, 246) = ( 1 x 246 ) / 246
= 1 / 246
= 1
So, Greatest Common Divisor of 855, 772, 289, 246 is 1
