GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(856, 206) = 88168
GCD(856, 206) = ( 856 x 206 ) / 88168
= 856 / 206
= 856
Step2:
LCM(2, 419) = 838
GCD(2, 419) = ( 2 x 419 ) / 838
= 2 / 419
= 2
Step3:
LCM(1, 672) = 672
GCD(1, 672) = ( 1 x 672 ) / 672
= 1 / 672
= 1
So, Greatest Common Divisor of 856, 206, 419, 672 is 1
