Given numbers are 605, 709, 387, 516
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(605, 709) = 428945
GCD(605, 709) = ( 605 x 709 ) / 428945
= 605 / 709
= 605
Step2:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
Step3:
LCM(1, 516) = 516
GCD(1, 516) = ( 1 x 516 ) / 516
= 1 / 516
= 1
So, Greatest Common Divisor of 605, 709, 387, 516 is 1
