Given numbers are 220, 418, 856, 397
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 418) = 4180
GCD(220, 418) = ( 220 x 418 ) / 4180
= 220 / 418
= 220
Step2:
LCM(22, 856) = 9416
GCD(22, 856) = ( 22 x 856 ) / 9416
= 22 / 856
= 22
Step3:
LCM(2, 397) = 794
GCD(2, 397) = ( 2 x 397 ) / 794
= 2 / 397
= 2
So, Greatest Common Divisor of 220, 418, 856, 397 is 1
