Given numbers are 194, 234, 689, 145
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(194, 234) = 22698
GCD(194, 234) = ( 194 x 234 ) / 22698
= 194 / 234
= 194
Step2:
LCM(2, 689) = 1378
GCD(2, 689) = ( 2 x 689 ) / 1378
= 2 / 689
= 2
Step3:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
So, Greatest Common Divisor of 194, 234, 689, 145 is 1
