GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(806, 198) = 79794
GCD(806, 198) = ( 806 x 198 ) / 79794
= 806 / 198
= 806
Step2:
LCM(2, 419) = 838
GCD(2, 419) = ( 2 x 419 ) / 838
= 2 / 419
= 2
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 806, 198, 419, 642 is 1
