GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(814, 112) = 45584
GCD(814, 112) = ( 814 x 112 ) / 45584
= 814 / 112
= 814
Step2:
LCM(2, 183) = 366
GCD(2, 183) = ( 2 x 183 ) / 366
= 2 / 183
= 2
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 814, 112, 183, 645 is 1
