GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(487, 856) = 416872
GCD(487, 856) = ( 487 x 856 ) / 416872
= 487 / 856
= 487
Step2:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
Step3:
LCM(1, 806) = 806
GCD(1, 806) = ( 1 x 806 ) / 806
= 1 / 806
= 1
So, Greatest Common Divisor of 487, 856, 644, 806 is 1
