GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(859, 643) = 552337
GCD(859, 643) = ( 859 x 643 ) / 552337
= 859 / 643
= 859
Step2:
LCM(1, 180) = 180
GCD(1, 180) = ( 1 x 180 ) / 180
= 1 / 180
= 1
Step3:
LCM(1, 419) = 419
GCD(1, 419) = ( 1 x 419 ) / 419
= 1 / 419
= 1
So, Greatest Common Divisor of 859, 643, 180, 419 is 1
