GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(672, 318) = 35616
GCD(672, 318) = ( 672 x 318 ) / 35616
= 672 / 318
= 672
Step2:
LCM(6, 243) = 486
GCD(6, 243) = ( 6 x 243 ) / 486
= 6 / 243
= 6
Step3:
LCM(3, 809) = 2427
GCD(3, 809) = ( 3 x 809 ) / 2427
= 3 / 809
= 3
So, Greatest Common Divisor of 672, 318, 243, 809 is 1
