Given numbers are 735, 861, 391, 307
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(735, 861) = 30135
GCD(735, 861) = ( 735 x 861 ) / 30135
= 735 / 861
= 735
Step2:
LCM(21, 391) = 8211
GCD(21, 391) = ( 21 x 391 ) / 8211
= 21 / 391
= 21
Step3:
LCM(1, 307) = 307
GCD(1, 307) = ( 1 x 307 ) / 307
= 1 / 307
= 1
So, Greatest Common Divisor of 735, 861, 391, 307 is 1
