Given numbers are 889, 385, 664, 427
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(889, 385) = 48895
GCD(889, 385) = ( 889 x 385 ) / 48895
= 889 / 385
= 889
Step2:
LCM(7, 664) = 4648
GCD(7, 664) = ( 7 x 664 ) / 4648
= 7 / 664
= 7
Step3:
LCM(1, 427) = 427
GCD(1, 427) = ( 1 x 427 ) / 427
= 1 / 427
= 1
So, Greatest Common Divisor of 889, 385, 664, 427 is 1
