Given numbers are 309, 447, 743, 516
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 447) = 46041
GCD(309, 447) = ( 309 x 447 ) / 46041
= 309 / 447
= 309
Step2:
LCM(3, 743) = 2229
GCD(3, 743) = ( 3 x 743 ) / 2229
= 3 / 743
= 3
Step3:
LCM(1, 516) = 516
GCD(1, 516) = ( 1 x 516 ) / 516
= 1 / 516
= 1
So, Greatest Common Divisor of 309, 447, 743, 516 is 1
