Given numbers are 145, 408, 832, 668
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(145, 408) = 59160
GCD(145, 408) = ( 145 x 408 ) / 59160
= 145 / 408
= 145
Step2:
LCM(1, 832) = 832
GCD(1, 832) = ( 1 x 832 ) / 832
= 1 / 832
= 1
Step3:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
So, Greatest Common Divisor of 145, 408, 832, 668 is 1
