GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 249) = 70965
GCD(855, 249) = ( 855 x 249 ) / 70965
= 855 / 249
= 855
Step2:
LCM(3, 847) = 2541
GCD(3, 847) = ( 3 x 847 ) / 2541
= 3 / 847
= 3
Step3:
LCM(1, 352) = 352
GCD(1, 352) = ( 1 x 352 ) / 352
= 1 / 352
= 1
So, Greatest Common Divisor of 855, 249, 847, 352 is 1
