Given numbers are 668, 249, 665, 160
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 249) = 166332
GCD(668, 249) = ( 668 x 249 ) / 166332
= 668 / 249
= 668
Step2:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
Step3:
LCM(1, 160) = 160
GCD(1, 160) = ( 1 x 160 ) / 160
= 1 / 160
= 1
So, Greatest Common Divisor of 668, 249, 665, 160 is 1
