GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 828) = 86940
GCD(945, 828) = ( 945 x 828 ) / 86940
= 945 / 828
= 945
Step2:
LCM(9, 339) = 1017
GCD(9, 339) = ( 9 x 339 ) / 1017
= 9 / 339
= 9
Step3:
LCM(3, 391) = 1173
GCD(3, 391) = ( 3 x 391 ) / 1173
= 3 / 391
= 3
So, Greatest Common Divisor of 945, 828, 339, 391 is 1
