GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(797, 653) = 520441
GCD(797, 653) = ( 797 x 653 ) / 520441
= 797 / 653
= 797
Step2:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
Step3:
LCM(1, 419) = 419
GCD(1, 419) = ( 1 x 419 ) / 419
= 1 / 419
= 1
So, Greatest Common Divisor of 797, 653, 689, 419 is 1
