GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(856, 230) = 98440
GCD(856, 230) = ( 856 x 230 ) / 98440
= 856 / 230
= 856
Step2:
LCM(2, 918) = 918
GCD(2, 918) = ( 2 x 918 ) / 918
= 2 / 918
= 2
Step3:
LCM(2, 450) = 450
GCD(2, 450) = ( 2 x 450 ) / 450
= 2 / 450
= 2
So, Greatest Common Divisor of 856, 230, 918, 450 is 2
