Given numbers are 351, 753, 620, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(351, 753) = 88101
GCD(351, 753) = ( 351 x 753 ) / 88101
= 351 / 753
= 351
Step2:
LCM(3, 620) = 1860
GCD(3, 620) = ( 3 x 620 ) / 1860
= 3 / 620
= 3
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 351, 753, 620, 789 is 1
