GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(529, 643) = 340147
GCD(529, 643) = ( 529 x 643 ) / 340147
= 529 / 643
= 529
Step2:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 529, 643, 809, 690 is 1
