GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(653, 485) = 316705
GCD(653, 485) = ( 653 x 485 ) / 316705
= 653 / 485
= 653
Step2:
LCM(1, 317) = 317
GCD(1, 317) = ( 1 x 317 ) / 317
= 1 / 317
= 1
Step3:
LCM(1, 842) = 842
GCD(1, 842) = ( 1 x 842 ) / 842
= 1 / 842
= 1
So, Greatest Common Divisor of 653, 485, 317, 842 is 1
