Given numbers are 843, 838, 649, 516
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(843, 838) = 706434
GCD(843, 838) = ( 843 x 838 ) / 706434
= 843 / 838
= 843
Step2:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
Step3:
LCM(1, 516) = 516
GCD(1, 516) = ( 1 x 516 ) / 516
= 1 / 516
= 1
So, Greatest Common Divisor of 843, 838, 649, 516 is 1
