Given numbers are 209, 756, 921, 487
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(209, 756) = 158004
GCD(209, 756) = ( 209 x 756 ) / 158004
= 209 / 756
= 209
Step2:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
Step3:
LCM(1, 487) = 487
GCD(1, 487) = ( 1 x 487 ) / 487
= 1 / 487
= 1
So, Greatest Common Divisor of 209, 756, 921, 487 is 1
