GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(653, 659) = 430327
GCD(653, 659) = ( 653 x 659 ) / 430327
= 653 / 659
= 653
Step2:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
Step3:
LCM(1, 843) = 843
GCD(1, 843) = ( 1 x 843 ) / 843
= 1 / 843
= 1
So, Greatest Common Divisor of 653, 659, 215, 843 is 1
