Given numbers are 397, 170, 427, 284
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 170) = 67490
GCD(397, 170) = ( 397 x 170 ) / 67490
= 397 / 170
= 397
Step2:
LCM(1, 427) = 427
GCD(1, 427) = ( 1 x 427 ) / 427
= 1 / 427
= 1
Step3:
LCM(1, 284) = 284
GCD(1, 284) = ( 1 x 284 ) / 284
= 1 / 284
= 1
So, Greatest Common Divisor of 397, 170, 427, 284 is 1
