Given numbers are 615, 655, 473, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(615, 655) = 80565
GCD(615, 655) = ( 615 x 655 ) / 80565
= 615 / 655
= 615
Step2:
LCM(5, 473) = 2365
GCD(5, 473) = ( 5 x 473 ) / 2365
= 5 / 473
= 5
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 615, 655, 473, 789 is 1
