Given numbers are 749, 166, 668, 401
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(749, 166) = 124334
GCD(749, 166) = ( 749 x 166 ) / 124334
= 749 / 166
= 749
Step2:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
Step3:
LCM(1, 401) = 401
GCD(1, 401) = ( 1 x 401 ) / 401
= 1 / 401
= 1
So, Greatest Common Divisor of 749, 166, 668, 401 is 1
